Photo-pollution disrupts reproductive homeostasis in female rats: The duration-dependent role of selenium administrations.

Although selenium is known to be essential for reproductive function, studies have indicated the adverse effect with its prolonged use. The present study investigated the duration-related effect of selenium administrations on reproductive hormones and estrous cycle indices in adult female Wistar rats exposed to a model of light pollution using altered photoperiod (AP). Ninety-six cyclic female Wistar rats displaying 4-5 days' estrous cycle length (ECL) and weighing 148-152 g were randomly divided into short and long experimental cohorts consisting of six groups each and spanning for 1 and 8 weeks, respectively.

Effect of Solanum Nigrun on Uterus of Non-gravid Rats.

Background: Solanum nigrum is a widely used plant in oriental medicine where it is considered to be antioxidant, anti- inflammatory and diuretic. This study aimed to evaluate the effect of Solanum Nigrum on uterine contractions.

Method: Female Wistar Wister albino rats were used for the study.

Antisickling and toxicological evaluation of the leaves of Scoparia dulcis Linn (Scrophulariaceae).

Background: Scoparia dulcis Linn (Scrophulariaceae) together with other medicinal plants serve as antisickling remedies in Africa. This study was aimed at investigating the antisickling activity of the leaves of the plant as well as establishing the toxicological profile.

Method: Chemical tests were employed in phytochemical investigations.

Antidiarrhoea and toxicological evaluation of the leaf extract of Dissotis rotundifolia Triana (Melastomataceae).

Background: The leaves of Dissotis rotundifolia are used ethnomedically across Africa without scientific basis or safety concerns. Determination of its phytochemical constituents, antimicrobial activity, effects on the gastrointestinal tract (GIT) as well as toxicological profile will provide supportive scientific evidence in favour of its continous usage.

Method: Chemical and chromatographic tests were employed in phytochemical investigations.

Thirst perception in dehydrated sickle cell disease patients in steady state.

Liberal fluid intake is one of the key management strategies in sickle cell anaemia [SCA] patients in steady state, but less work has been done on the desire of patients to drink water. Using the Visual Analogue Scale we studied thirst perception [TP] in 20 euhydrated SCA patients and 28 control [HbA] subjects, as well as during dehydration in 13 SCA patients and 9 HbA subjects. Serum and urine samples were collected and analyzed for Na, K ions, creatinine concentrations and haematocrit and specific gravity of urine were determined.

Antimicrobial and toxicological evaluation of the leaves of Baissea axillaries Hua used in the management of HIV/AIDS patients.

Background: Persistent diarrhea is a common endemic disease with high incidence among the Africans including Nigerians. It also represents a frequent opportunistic disease in people living with HIV. Diarrhea represents one of the most distressful and persistent symptoms of HIV/AIDS, which may or may not be accompanied by an infection.

Effects of halofantrine hydrochloride (halfan) on the histology of the ovary of mature female Wistar rats.

Halofantrine hydrochloride (halfan) was administered via oral route to matured female wistar rats weighing 180-200 g. The Wistar rats were randomly selected and divided into six groups of four rats each, making a total of twenty four rats and coded A1, A2, A3, B1, B2 and B3. Groups A3 and B3 were used as controls.
