Abstract
OBJECTIVES Although the adipocyte protein leptin has been implicated in the control of reproductive function in rodents, its role in primate reproductive physiology is poorly understood. Because primates in puberty show nighttime LH secretion and there is considerable evidence that the fertile state requires adequate nutrition, we reasoned that animals on the verge of reproductive competence would respond to leptin infusions by secreting LH. Food restriction reduces circulating leptin levels and slows or stops the GnRH pulse generator. Therefore, we examined the endocrine effects of leptin infusions in food-restricted male pubertal primates during the night when they normally secrete LH. In addition, we investigated the effect of leptin on in vitro testosterone production by Leydig cells. SUBJECTS Four pubertal male rhesus macaques (Macaca mulatta), 4-5.5 kg in weight (2.5-4-year-old) were examined in this study. Leydig cells from adult male rats were to investigate in vitro effects of leptin. DESIGN To document that animals had entered puberty, blood samples were collected from each of the four animals at 15-minute intervals for 15 h both during the day and at night. Since at this age animals secrete LH mainly at night, blood samples were collected at 15-minute intervals from each of the four animals on two separate occasions for 15 h between 1500 and 0600h. During the experiment, animals were feeding from 0800 to 0830h, cages were completely cleaned of food at 0900h and the afternoon meal was not given to individual animals on the day they were studied. One of the studies served as the control (food restricted group) and during the other, 2 mg (n = 4) or 0.3 mg (n = 3) of recombinant human leptin was administered intravenously during 2000-0100h (food restricted plus leptin group). Blood samples (1 ml) were collected through the indwelling catheter and immediately transferred from the plastic syringe into chilled glass tubes containing 10 microl 14% EDTA. The samples were centrifuged at 5-h intervals and the plasma withdrawn and stored frozen at - 20 degrees C in polypropylene vials until assays were performed. MEASUREMENTS Bioactive LH was determined and testosterone, cortisol and leptin were measured by radioimmunoassay. RESULTS During daytime experiments in these animals, LH pulses were sometimes observed late in the day and generally continued for 12-15 h. Food-restricted pubertal males showed delayed or absent LH pulses. Short-term leptin administration to food-restricted male rhesus macaques had no effect on LH, testosterone, or cortisol levels either during or after the infusion. Leptin also had no direct effect on basal or LH-stimulated testosterone production in Leydig cells. CONCLUSIONS Our data support the notion that leptin is not the missing signal for the acute suppression of reproductive hormones secretion in food-restricted primates.

Abstract
A murine hybridoma was generated which secreted a monoclonal antibody (Mab) that specifically recognized the alpha 2(68)(E17)Asn----Lys beta 2 substitution of Hb G-Philadelphia. Hybridomas were produced by fusion of RBF/DnJ immune splenic lymphocytes with FOX-NY murine myeloma cells and selected in adenine-aminopterin-thymidine (AAT) medium. Culture fluids were screened by ELISA for antibody reacting with Hb G-Philadelphia but not Hb A. One such culture was cloned by limiting dilution, expanded and injected into pristane-primed, cyclophosphamide-suppressed BALB/c mice for ascites production. An enzyme-linked immunoassay was developed by conjugating hemoglobin in hemolysates or purified hemoglobins to the plastic surface of wells of a microtiter plate. The ascites fluid containing the Hb G-Philadelphia Mab was added to the wells followed by goat anti-mouse IgG conjugated with horseradish peroxidase. After the addition of substrate (tetramethylbenzidine), a deep blue color developed, signifying a positive reaction. We analyzed 58 hemolysates (17 adult, 41 cord) containing a G-variant along with 28 control hemolysates (12 cords comprising FA, FAC, FAS, FSS, FCC phenotypes; 16 adults consisting of AA, AS, SS, SC, S-beta thal, AD-Los Angeles phenotypes). Of the 58 hemolysates containing a G-variant, 53 were positive by ELISA and confirmed by radioimmunoassay (RIA). Four of the five hemolysates negative for Hb G-Philadelphia were shown to be Hb G-Montgomery by RIA. None of the control hemolysates were positive. The assay could be completed in 1 hr and represents a technological advance in hemoglobin identification.

Abstract
A 10 year study of cauliflower growths in trophic ulcers of leprosy patients was done. Seventy five cases were seen, out of which seventy two were in foot and three in hand. Eventhough appearance was like that of malignancy, malignant change was seen only in four cases and in other seventy one cases it was pseudoepitheliomatous hyperplasia. Various surgical procedures were done. Wide excision appears to be the procedure of choice where feasible as per our studies.

Abstract
This paper describes three hierarchical organizations of small processors for bottom-up image analysis:pyramids, interleaved pyramids, and pyramid trees. Progressively lower levels in the hierarchies process image windows of decreasing size. Bottom-up analysis is made feasible by transmitting up the levels quadrant borders and border-related information that captures quadrant interaction of interest for a given computation. The operation of the pyramid is illustrated by examples of standard algorithms for interior-based computations (e.g., area) and border-based computations of local properties (e.g., perimeter). A connected component counting algorithm is outlined that illustrates the role of border-related information in representing quadrant interaction. Interleaved pyramids are obtained by sharing processors among several pyramids. They increase processor utilization and throughput rate at the cost of increased hardware. Trees of shallow interleaved pyramids, calld pyramid trees, are introduced to reduce the hardware requirements of large interleaved pyramids at the expense of increased processing time, without sacrificing processor utilization. The three organizations are compared with respect to several performance measures.
