With first permanent molar impaction, less advanced calcification of the second permanent molars, and smaller overall dimensions than the normal age controls. The undernourished animals at the same age had a lesser degree of jaw growth, more retarded dental development and greater tooth impaction than did the animals with kwashiorkor. Similar features were observed in the intervening stages examined up to 1 year. Evidence suggests -that pigs with supplementary carbohydrate, but an even lower protein intake, achieve a similar dental development to those on a higher protein intake, but with smaller craniofacial growth and increased overcrowding.
The observed regioselectivities and enable the identification of the major structural and chemical factors that determine the preferred methylation sites. Finally, the X-ray structure of the complex of COMT with SAM and BIA 8-176 is herein disclosed, and some structural and dynamic aspects of this complex are analyzed and discussed. The analysis of docking calculations indicates that the geometry of the enzyme-inhibitor complex is primarily determined by the nitrocatechol moiety. Although this molecular fragment may potentially adopt either ortho or meta configurations within the catalytic pocket, our calculations indicate that the meta poses should be energetically penalized as a result of sterically conflicting interactions between the nitro group and the side chain of Leu198 and repulsive electrostatic forces with the negatively charged Glu199. Conversely, the nitro group can be easily accommodated at the opposite side of the catalytic pocket, in the ortho configuration, where it establishes favorable van der Waals contacts with Trp143. The results suggest that interactions involving the benzoyl side chain may also affect the energetic balance between ortho and meta poses. Their contribution should however, be considerably less determinant than those of the nitrocatechol moiety. The simultaneous contributions of the nitro and benzoyl substituents within the structures of the two regioisomers, may result in the potentiation or the attenuation of the energy gaps between the ortho or meta complex configurations. In the case of BIA 8-176, where the benzoyl occupies the ortho position relative to the nitro group, the effects of the two substituents are additive with respect to the influence they exercise on determining the binding geometry. Therefore, this complex presents a greater binding regioselectivity with the ortho configuration greatly favored in relation to the "meta complex". The meta-nitrated inhibitor BIA 3-228, on the other hand, shows a distinct behavior. Even though the ortho bound configuration is still energetically favorable, the effects of the two substituents on the binding geometry are partially self-compensatory, and the energy difference between ortho and meta poses is relatively attenuated. The regioselectivity of binding predicted for this complex, is therefore less pronounced than that expected between COMT and BIA 8-176. Although the relative position of attachment of the benzoyl group to the catechol ring may have a limited influence on the geometry of binding of the inhibitor within the catalytic site, it is suggested that it will have a profound impact on the chemical reactivity of the two hydroxyl groups. Electronwithdrawing substituents on the catechol ring contribute to the delocalization of the excess electron density, away from the reactive ionized catecholate oxygen. In this way, such groups lower the nucleophilicity of the hydroxyls and hence reduce their propensity to react with the electron-deficient methyl group from SAM. It is demonstrated that the relative positions of the two substituents strongly affect the nucleophilicity balance between the two hydroxyl groups. In the meta-nitrated molecule BIA 3-228, the benzoyl and the nitro substituents exert a combined inductive effect that is maximal on the catecholate hydroxyl oxygen found ortho to the nitro and para to the benzoyl substituent ; . Therefore, the reactivity of this hydroxyl is strongly diminished, compared with that of the unsubstituted catechol Fig. 7 ; . On the contrary, the second hydroxyl function, which is meta to both substituents, is the least perturbed and therefore should be.
ZACHARY T. BLOOMGARDEN, MD betes develop foot ulcers, and 6% of individuals with diabetes require hospitalization for these, at "astronomical" cost. Further, it is necessary to correct the foot deformities rather than just get the ulcer to heal. This may require as little an intervention as an Achilles tendon lengthening. Similarly, vascular evaluation is required for these patients to promote wound healing. "One can keep the wound healed with the proper mechanics, " Cohen pointed out, but ongoing patient involvement is crucial, with education and efforts to involve patients in their own care. Discussing the role of growth factors in diabetic ulcers, Cohen noted that platelet-derived growth factor PDGF ; is produced in wounds at the time of injury by many cellular elements in addition to platelets and that there are many other cytokines that act along with it and may be found to have a therapeutic role. It is chemotactic, stimulating proliferation of fibroblasts and smooth muscle cells, production of collagen, and angiogenesis. It is only effective after full debridement. He pointed out that wounds produce elastase, collagenase, and other proteases, which "totally wipe out" cytokines as well as their receptors, so topical application of growth factor may be of limited benefit. "One has to debride the ulcer well, " Cohen stated, totally excising bacterial products, including proteases, to make a clean wound; and in certain cases, grafts, local flaps, or free-tissue transfers with microvascular surgery may be needed to salvage the extremity. PDGF is effective, although Cohen suggested his reservations regarding the health-economic data that has been cited to suggest it is worthwhile. He noted that in the reported study the site with the highest debridement rate had the highest healing rate and the site with the lowest debridement rate had the lowest healing rate, showing the importance of this local treatment. "The Achilles heel of [this approach] is wound protease, " he pointed out, but with appropriate deDIABETES CARE, VOLUME 24, NUMBER 5, MAY 2001.

A method that our office developed for Carl Zeiss Meditec, Inc. Dublin, CA ; , years ago, in which the operator takes multiple readings around the measurement reticule, looking to find the location that returns the best axial-length display. All 20 measurements are taken, the best axial-length display is identified, and then all measurements greater than 0.02 mm on either side of this ideal measurement are discarded. For the last method, we took 20 measurements and let the machine analyze them without any input from the operator. A slightly greater number of the patients were male, their mean age was 75 years, and 61% had vision that was between 20 40 and 20 200. All pseudophakic eyes were excluded. Eleven percent of the eyes had vision of less than 20 200, and more than 9% had finger counting or light-perception cataracts. All cataracts were graded by the Lens Opacities Classification System III as described in the Archives of Ophthalmology in June 1993.1 The final results were then stratified by lens color and other criteria. The standard method of taking five measurements and calculating the arithmetic mean produced the results we expected: not great. A little more than half of the eyes could be measured. When we gave the machine five consecutive measurements and allowed the IOLMaster to arrive at a composite value, more than 92% of patients were successfully measured. When we used our usual method of sampling multiple areas, combined with deleting outliers, 94% of patients could be successfully measured. Finally, when we took 20 measurements and simply allowed the IOLMaster software to arrive at its own conclusions, more than 96% of eyes were successfully measured. It is helpful to keep in mind that more than 9% of these eyes had count-fingers or light-perception visual acuity.

Dermatology Associates of Cincinnati, Inc., Mercy Health Plaza, Beechmont at Five Mile Road, 7691 Five Mile Road, Cincinnati, OH 45230 ABSTRACT: Oral lichen planus is a chronic mucocutaneous disease that is relatively common. Although many patients are asymptomatic and require no therapy, those who exhibit atrophic and erosive lesions are often a challenge to treat. All therapies are palliative, and none is effective universally. Currently employed treatment modalities include corticosteroids administered topically, intralesionally, or systemically. Alternative therapies include topical and systemic retinoids, griseofulvin, Cyclosporine, and surgery. Other medical treatments and experimental modalities, including mouth PUVA, have been reported to be effective. Controversy concerning the efficacy of all these treatments suggests that oral lichen planus is a heterogeneous disorder. Eliminating lichenoid drug eruptions, candidiasis, trauma, contact mucositis, and emotional stress may play a role in the management of these patients. This article is a review of the many treatments and measures that have been employed in the management of patients with oral lichen planus. KEY WORDS: oral lichen planus, corticosteroids, retinoids, Cyclosporine, griseofulvin, Dapsone, PUVA and nadolol.

In dogs given 62.5-250 mg kg bid of ZDV po for 14 days, cytostatic effects were seen in certain tissues with rapid cell replication rates bone marrow, gastrointestinal epithelium, lymphoid tissue ; . The clinical signs in these animals diarrhea, anemia, leukopenia, thrombocytopenia, and at the highest dose, death ; were considered to be secondary to cytostatic effects seen in these tissues. Cytostatic effects were not seen when identical doses were given to monkeys in a 2-week oral dose range-finding study. Similarly, doses of 225-250 mg kg bid did not induce cytostatic effects in 3-, 6-, and 12-month studies in rats. Why the dog is more sensitive to ZDV than the monkey or rat is not known. It has been our experience, however, that dogs are more sensitive in general to the effects of nucleoside analogs than some other species. For example, high doses of acyclovir, the anti-herpes nucleoside analog, caused toxic effects in dogs similar to those seen with ZDV Tucker et al., 1983 ; . Toxicity with acyclovir was less severe in rodents. It should also be noted that dogs are more sensitive to the effects of ionizing radiation than are rats or monkeys. Bond et al. 1969 ; showed that the LDso for acute whole body radiation was two- to threefold greater for rats and monkeys than for dogs. Species differences in metabolism or pharmacokinetics are not thought to have influenced toxicity. As has been shown, a smaller percentage of a dose of ZDV is metabolized to GZDV in dogs than in monkeys. At a given dose level, therefore, plasma concentrations of ZDV would be expected to be higher in the dog than the monkey. One might be.

And large-scale clinical trials are currently under way, with a probability of U.S. Food and Drug Administration approval within the next year or so. Relatively little is known about the effects of brachytherapy in the venous system and hemodialysis circuits. A clinical trial of gamma brachytherapy in patients with failing hemodialysis grafts is reportedly under way 32 ; , but results of this trial are not yet available. Smith et al 22 ; reported a trend toward reduction of intimal hyperplasia at 1 month in a sheep arteriovenous graft model with a rhenium 186filled balloon a beta emitter ; . Waksman et al 23 ; reported results of a pilot study in failing human hemodialysis grafts. They used 192Ir following balloon angioplasty at a dose of 14 Gy grafts in 11 patients. At a mean follow-up of 44 weeks, 11 of 18 sites remained patent. These preliminary human data are not particularly promising, although the authors indicated they believed suboptimal centering accounted for the poor results. Nowhere is a feasible approach to the reduction of restenosis needed more than in hemodialysis access. Even the best results of balloon angioplasty in hemodialysis-related venous stenosis are measured in months, with a 38%63% 6-month primary patency rate reported in several large series 36 ; . Currently available vascular stents appear to be no better than balloon angioplasty, as determined in three prospective randomized trials 1012 ; . Medical treatments designed to reduce restenosis in hemodialysis access have been equally disappointing 2 ; . The results of our study suggest a possible role for brachytherapy in hemodialysis accessrelated stenosis. Gamma brachytherapy in this established animal model yielded significant reductions in in-stent restenosis, as measured as maximum percentage stenosis measurements at multiple time points during the study, with a consistent trend toward reduction even when statistical significance was not achieved. This effect was confirmed by volumetric computer modeling, which we believe more accurately conveys the difference in volume of intimal hyperplasia as opposed to stenosis at a single site. However, in the single animal followed up for 1 year, the treated side became the more stenotic side at 9 months. It should be noted that this late reversal could conceivably indicate a delayed detrimental effect of brachytherapy, which will need even longer-term studies to evaluate. Since this represents only a single.

In North America and Europe there has been an unprecedented increase in litigation relating to animals over the past ten years. Legal cases mainly concern such issues as cause of death, welfare, provenance, aging and parentage. Protected species of wildlife acan be the subject of litigation, as well as domesticated species. Forensic veterinary medicine, defined here as the application of veterinary knowledge to the purpose of the law, is a rapidly evolving subject that will increasingly influence all veterinarians who deal with captive or free-living animals. The requirements of special requirements and demands of veterinary forensic work are also relevant to insurance claims and allegations of professional misconduct. Certain aspects of animal forensic work may need to be the responsibility of the specialist pathologist, toxicologist, or DNA technologist, but all veterinary practitioners must have some familiarity with the subject. Important requirements when dealing with forensic cases in the practice are the use of standard techniques, meticulous investigations, proper labelling and storage of samples, and detailed record-keeping. A field in which forensic evidence from veterinary surgeons is likely to become increasingly important concerns the apparent links between animal abuse, child abuse and domestic violence. Part of this involves the recognition by clinicians of "non-accidental injuries" in animals but the issue has wider implications for the profession as a whole and can require close contact with other groups, including pediatricians, social workers, teachers and police officers. New fields of veterinary forensic activity are emerging on account of concern over global pollution and decline in biodiversity and the public's insistence that action should be taken regarding illegal and irresponsible damage to the planet. Although forensic work associated with wildlife conservation is currently primarily restricted to species protection, safeguarding the environment is likely to involve the veterinarian to a greater extent than ever before. Forensic medicine offers exciting challenges, but is as yet not a bona fide discipline within the veterinary curriculum and thus not given recognition as a specialist subject. This lack of status, coupled with a paucity and scattering of literature and data, hampers the ability of the veterinarian to contribute adequate his or her skills and knowledge. It is especially important that practitioners are aware of the potential of litigation and that they orientate their day-to-day activities, especially the examination of suspect or particularly valuable animals, accordingly. Any consultation, any treatment, any giving of an opinion, may lead to a legal or disciplinary case. It is prudent, therefore, for veterinary practices to introduce graded standard operating procedures for example, based on a traffic-light system - to help to alert staff to the possibility of legal consequences and ensure that appropriate precautions and safeguards are put into place and mycostatin.
