ABSTRACT
Estudaram-se os efeitos da geleia real sobre a espermatogênese de coelhos tratados com diferentes concentrações de geleia real. Os tratamentos foram formados por três grupos: grupo-controle; grupo que recebeu 0,5mg/dia de geleia real; e grupo que recebeu 1,0mg/dia de geleia real. O estudo envolveu a morfometria testicular. Não houve diferença entre os tratamentos quanto aos pesos corporal (T1=3,20±0,19kg, T2=2,96±0,30kg e T3=3,21±0,37kg) e gonadal (T1=2,36±0,33g, T2=2,53±0,33g e T3=2,64±0,39g) e quanto aos índices gonadossomático (T1=0,15±0,02%, T2=0,17±0,03% e T3=0,16±0,02%) e tubulossomático (T1=0,06±0,01%; T2=0,07±0,01% e T3=0,06±0,01%). O diâmetro médio dos túbulos seminíferos (T1=225,95±13,27µm, T2=239,68±21,50µm e T3=231,57±15,94µm), a altura do epitélio seminífero (T1=66,05±5,37µm, T2= 73,47±9,11µm e T3=63,34±4,79µm) e o comprimento de túbulos seminíferos por testículo (T1=46,63±13,44m, T2=43,58±12,17m e T3=46,96±9,54m) e por grama de testículo (T1=19,50±2,68m, T2=17,12±3,91m e T3=17,78±1,98m) não diferiram entre tratamentos. Conclui-se que a suplementação com geleia real, nas doses utilizadas, não altera as características testiculares avaliadas.
This study aimed to investigate the effects of royal jelly on spermatogenesis in rabbits treated with different concentrations of RJ (Control; 0,5mg/day; and 1,0mg/day) using testicular morphometry. There was no significant difference between the body weight (T1= 3.20±0.19kg; T2= 2.96±0.30kg; T3=3.21±0.37kg) and gonadal weight (T1= 2.36±0.33g; T2= 2.53±0.33g; T3= 2.64±0.39g), gonadossomatic index (T1= 0.15±0.02%; T2= 0.17±0.03%. T3= 0.16±0.02%) and tubulossomatic index (T1= 0.06±0.01%; T2= 0.07±0.01%. T3= 0.06±0.01%) between treatments, showing that the percentage of body mass, and the percentage of seminiferous tubules allocated in testis were similar in the 3 experimental groups. Similarly, the mean diameter of the seminiferous tubules (T1= 225.95±13.27µm; T2=239.68±21.50µm; T3= 231.57±15,94µm), the height of the seminiferous epithelium (T1=66,05±5,37µm; T2=73.47±9.11µm; T3=63.34±4.79 µm) and length of seminiferous tubule for testis (T1=46.63±13.44m; T2=43.58±12.17m; T3=46.96±9.54m) and per gram of testis (T1=19.50±2.68m; T2=17.12±3.91m; T3=17.78±1.98m) did not differ statistically. It was concluded that supplementation with royal jelly, at the doses used, did not alter the testicular parameters evaluated here.

This study determined the effects of gallium-aluminum-arsenide laser (GaAlAs), gallium-arsenide laser (GaAs) and Dersani® healing ointment on skin wounds in Wistar rats. The parameters analyzed were: type I and III collagen fiber concentrations as well as the rate of wound closure. Five wounds, 12 mm in diameter, were made on the animals backs. The depth of the surgical incision was controlled by removing the epithelial tissue until the dorsal muscular fascia was exposed. The animals were anesthetized with ketamine and xylazine via intraperitoneal injection. The rats were randomly divided into five groups of 6 animals each, according to the treatment received. Group 1 (L4): GaAs laser (4 J/cm²); group 2 (L30): GaAlAs laser (30 J/cm²); group 3 (L60): GaAlAs laser (60 J/cm²); group 4 (D): Dersani® ointment; group 5 (control): 0.9 percent saline. The applications were made daily over a period of 20 days. Tissue fragments were stained with picrosirius to distinguish type I collagen from type III collagen. The collagen fibers were photo-documented and analyzed using the Quantum software based on the primary color spectrum (red, yellow and blue). Significant results for wound closing rate were obtained for group 1 (L4), 7.37 mm/day. The highest concentration of type III collagen fibers was observed in group 2 (L30; 37.80 ± 7.10 percent), which differed from control (29.86 ± 5.15 percent) on the 20th day of treatment. The type I collagen fibers of group 1 (L4; 2.67 ± 2.23 percent) and group 2 (L30; 2.87 ± 2.40 percent) differed significantly from control (1.77 ± 2.97 percent) on the 20th day of the experiment.

Avaliaram-se os efeitos da geleia real sobre os parâmetros morfofisiológicos testiculares de camundongos (Mus musculus). Utilizaram-se 57 machos Swiss, com quatro meses de idade, distribuídos aleatoriamente em seis tratamentos: T1: solução fisiológica, via intraperitoneal; T2: 0,1mg de geleia real, via intraperitoneal; T3: 0,2mg de geleia real, via intraperitoneal; T4: água destilada, via oral; T5: 0,1mg de geleia real, via oral; e T6: 0,2mg de geleia real, via oral. Após 45 dias de suplementação com geleia real, os animais sacrificados e pesados tiveram seus testículos coletados, incluídos em parafina e corados com hematoxilina/eosina. Não houve diferença entre os tratamentos quanto aos: pesos corporal e testicular, índice gonadossomático, diâmetro tubular, altura do epitélio, comprimento total dos túbulos seminíferos, comprimento tubular por grama de testículo, índices tubulossomático e leydigossomático e valores de proporção volumétrica referentes à túnica própria, epitélio seminífero, vaso sanguíneo e vaso linfático. Foi encontrada diferença entre T1 e T3 em relação aos túbulos seminíferos e ao espaço intertubular.
The effects of royal jelly on the morphophysiological parameters of mice (Mus musculus) testicles were studied. Fifty-eight male Swiss mice were evaluated. They were four-month old and were randomly distributed in six treatments: T1: physiological solution, intraperitonial route; T2: 0.1mg of royal jelly, intraperitonial route; T3: 0.2mg of royal jelly, intraperitonial route; T4: distilled water, orally; T5: 0.1mg of royal jelly, orally; and T6: 0.2mg of royal jelly, orally. After 45 days of supplementation with royal jelly, the animals were weighted, slaughtered, and the testicles collected, included in paraffin, and stained with haematoxylin-eosin. No differences among treatments were observed for: body and testicular weights, gonadossomatic index, tubular diameter, epithelial height, total length of seminiferous tubules, tubular length per testicle gram, tubulossomatic and leydigossomatic indexes and the value of volumetric proportion related to tunic, seminiferous epithelium, blood vessel, and lymphatic vessel. Differences between T1 and T3 about the seminiferous tubules and intertubular space were found.

Rabies is an ancient disease of mankind. Every year 4 million people are exposed worldwide after animal bite and around 60000 fell victim to the rabies of which more than 95% of cases are bitten by the dogs. Rabies is a disease associated with many myths. The present study was conducted to find out the clinical profile of the animal bite cases including the common practices, precautions adopted by them after animal bite and lastly the extent and completion of post exposure treatment. Total 147 cases of animal bites attended the OPD during the study. In present study, 123 (83.7%) cases were bitten by dogs, followed by monkey (8.2%) and cat (8.2%). Majority (54.4%) suffered class II bites followed by class I (31.3%) and class III bite (14.3%). Of the total 147 cases, 116 cases (78.9%) completed post exposure prophylaxis which was observed higher among male and in younger age group.

BACKGROUND & OBJECTIVES: Knowledge about malaria, attitude and health seeking behaviour of fever patients attending Medicine Out Patient Department at Safdarjang Hospital, New Delhi were studied from June to August 2003. METHODS: Cross-sectional survey comprising 200 fever cases was done with prestructured and pretested questionnaire. Data on sociodemographic profile, history of fever, health seeking behaviour, etc were recorded. RESULTS: About 83% of fever cases did not approach the doctor even after three days of onset of fever symptom, 25.5% tried self medication and 20.5% approached chemists for treatment. Knowledge about causes and prevention of malaria was found to be inadequate in the study subjects. INTERPRETATION & CONCLUSION: Knowledge about malaria is poor even in persons residing in urban localities and proper health education is required for successful control of malaria. Information, education and communication activities are indicated to create awareness among the community.

Foram utilizados ovários de lambaris-bocarra (Oligosarcus argenteus) no estágio de maturaçäo avançada, para a caracterizaçäo citoquímica da zona pelúcida (ZP). Esta estrutura foi observada a partir do ovócito II surgindo como uma camada única, acidófila e PAS positiva. A partir do ovócito III, a ZP apresentou duas camadas, sendo que a externa, embora mais fina, reagiu mais intensamente ao PAS. Nos ovócitos IV, a ZP exibiu estriaçöes e grânulos de glicogênio aderidos à sua superfície interna. A reaçäo positiva ao PAS indicou a presença de polissacarídeos/glicoproteínas neutras na zona pelúcida

Eighty children with bronchial asthma and ten control cases underwent radionuclide gastroesophagography for the detection of gastroesophageal reflux. Thirty nine per cent asthmatic children demonstrated esophageal reflux on scintiscanning. The ten control subjects had no reflux. The presence of reflux correlated strongly with the presence of nocturnal exacerbation of symptoms. Bronchodilator therapy did not affect the prevalence of GER in asthmatic children.
