testosterone enanthate (te) is used by many athletes as a muscle builder. previous studies showed that high concentration of the drug in plasma may affect the natural function of endocrine glands, specially the secretion of the adrenocortical hormones. the objective of the present study was to examine the effects of high concentration of te on histometrical structure of adrenal cortex in male r...

INTRODUCTION The purpose of this study was the estimation of foetal femoral bone development, based on anthropometric, densitometric and histometric examination. MATERIAL AND METHODS The study was done on 68 foetuses (31 female and 37 male) of various foetal ages (16-31 weeks of gestation). The specimens, ranging 16-31 weeks of gestation, were divided into 3 groups for better statistical anal...

The aim of this study was to evaluate the periodontal response to subgingival restorations in dogs with naturally occurring periodontitis. At the baseline, the experimental teeth from three dogs (2nd and 3rd upper premolars and 2nd, 3rd and 4th lower premolars) were randomly assigned to Resin-modified Glass Ionomer Cement (RMGIC) and Amalgam (AM) restorations or controls (CT) at the buccal site...

OBJECTIVE The purpose of this study was to perform histological and histometric analyses of the repair process of autogenous bone grafts fixed at rat calvaria with ethyl-cyanoacrylate adhesive. MATERIAL AND METHODS Thirty-two rats were divided into two groups (n=16), Group I - Control and Group II - Adhesive. Osteotomies were made at the right parietal bone for graft obtainment using a 4-mm-d...

Chromium has been recognized as a new and important micro-nutrient, essential for both human and animal nutrition. This study was conducted to evaluate the appropriateness and/or the use of safety level of dietary chromium picolinate (Cr-Pic), and its effects on the physiological responses, the histometric characteristics, and the chemical analysis of dorsal muscles of mono-sex Nile tilapia, Or...

Histological and histometric changes in the testes of albino Wistar rats were correlated. Wistar rats weighing between 180-240 g were randomly divided into three groups of ten rats each. One group served as control and the rats were given normal saline. The second and third groups received 2 mg/kg and 4 mg/kg body weights of chloroquine phosphate daily for thirty days respectively. Seminiferous...

OBJECTIVE The aim of this study was to compare subgingival irrigation with tetracycline hydrochloride (TTC-HCL) as adjunctive treatment to scaling and root planning (SRP) on induced periodontitis in rats. MATERIAL AND METHODS In 60 rats, periodontal disease was ligature-induced at the mandibular left first molar. After 7 days, the ligature was removed and all animals were submitted to SRP, an...

Methods: Twenty-four rats were divided into 4 groups, according to the treatment received over the 13 days before and after ligature insertion around first lower molar in order to induce periodontal disease (PD): Ss (Simvastatin-Simvastatin); Sw (Simvastatin-Water); Ws (Water-Simvastatin) and Ww (Water-Water). Simvastatin was administered by gavage (35mg/Kg/day). After euthanasia, radiographic,...
