1. The effects of retinol and retinoic acid supplementation of retinol-deficient rats were studied for a variety of metabolic processes shown to be affected by retinol-deficiency. 2. Retinol-deficient rats were found to have decreased body-weight, liver and testes weights, a degeneration of testicular germinal cells, an increased incorporation of labelled choline into liver and testes phospholi...

The relationship between the plasma concentration of morphine and morphine-induced changes in ventilation and the ventilatory response to carbon dioxide was studied in 17 healthy adults undergoing elective surgery under general anaesthesia. Each subject was given morphine sulphate 0.15 mg kg-1 i.m.; ventilation (Ve), end-tidal PCO2(PE'CO2), mixed venous PCO2(PVCO2) and ventilatory response to c...

The possible toxicity of a commercial chlorine dioxide preparation (Halox E-100) was evaluated on radish and lettuce seedlings growing in pots under controlled conditions. A single application of various dilutions to radish seedlings growing in a sterile or nonsterile commercial plant substrate only slightly decreased plant dry weight. At the end of the experiments, the plants appeared unaffect...

BACKGROUND Our previous studies revealed Anethum graveolens L. caused some changes in female reproductive system that induced infertility. Therefore, in this study, oocyte changes as one of probable reasons of infertility were investigated. METHODS In this study, 59 adult female rats were divided into 3 groups of control, low dose (0.5 g/kg) and high dose (5 g/kg) of dill seed aqueous extract...

OBJECTIVE Medicinal plants have attracted global attention due to their safety as well as their considerable antioxidant content that helps to prevent or ameliorate various disorders including memory impairments. This study was conducted to investigate the effect of beet root (Beta vulgaris) leaf extract on scopolamine-induced spatial memory impairments in male Wistar rats. MATERIALS AND METH...

background: hoxa11 and hoxa10 are expressed in endometrium throughout the menstrual cycle and show a dramatic increase during the mid-luteal phase at the time of implantation. the expression of these genes is decreased in women with myomas. objective: to determine whether myomectomy would reverse hoxa11 and hoxa10 expression, we evaluated the transcript levels of these genes in the endometria o...

the objective of this study was to evaluate the effect of process conditions and different pretreatments including ultrasound, microwave and osmotic dehydration on mass transfer and oil uptake during deep fat frying of potato slices. ultrasound pretreatment was performed at frequency of 40 khz for 10 and 30 minutes, microwave pretreatment was conducted at 5 w/g power and osmotic dehydration pre...

Background: -Fasting, the voluntary abstention from all restricted foods, is a feature of many religions, and the putative health benefits have attracted both scientific and popular interest. There is no clear understanding that religious fasting has great effects on metabolic syndrome. There is little data available that provides information concerning Ethiopian Orthodox Christians fasting inf...

Cobalamin (vitamin B₁₂) deficiency occurs with several disorders, involving different organs and systems, including blood, bowel, nervous system and eyes. Although the most important features are usually haematological ones, presence of neurological involvement, in the absence of blood count alterations, has just been described in the literature. Here we report the case of a 48-year-old man, su...

Concanavalin-A-induced T-suppressor cell activity was decreased in spleen cell suspensions from Lewis rats with adjuvant arthritis. This decreased activity was evident on day 10 after the induction of the disease, just before the development of the polyarthritic lesions, and persisted during the period of active inflammatory and immunological disease. The extent of the impairment of T-suppresso...
