Background: The extract of Corchorus olitorius has a reasonable content of vitamins A and C, calcium, iron and fibre, and therefore enjoys a universal application in the treatment of some disease conditions, even as the whole leaf is a very important component of food in so many cultures. Purpose: The study was designed to investigate the effect of Corchorus olitorius extracts on the testis of adult Wistar rats. Method: A total number of thirty two adult Wistar rats weighing between 180 and 200 grammes separated into four groups labeled A,B,C and D respectively were used for the study. Animals in group A which served as the control group were fed with the normal rat chow and water only. The group B rats were administered 100mg/kg body weight of aqueous extract of Corchorus olitorus; while those in group C were administered 500mg/kg body weight of the extract. The group D rats received 1000mg/kg body weight of the extract. For a period of four weeks, the different experimental animal groups received the respective aforementioned treatments once daily, around nine- o’clock in the morning through oral intubation. At the end of the 28 day treatment, the animals were sacrificed and the testes harvested for histological, investigation, and through cardiac puncture, blood samples for some hormonal studies was also collected and investigated using standard laboratory standards. Results: Observations made showed that the extract produced no histological distortions, degenerative or defective effects on the testicular tissues. The testosterone levels of group B, C, and D rats were observed to be significantly higher (P<0.005) than that of the group A (control group).ound: The extract of Corchorus olitorius has a reasonable content of vitamins A and C, calcium, iron and fibre, and therefore enjoys a universal application in the treatment of some disease conditions, even as the whole leaf is a very important component of food in so many cultures.

The organophosphate, dichlorvous (Otapia-pia) formulated in varying concentrations as insecticides is utilized by several individuals in most remote places of Nigeria due to its affordable value and accessibility. However, this present study is conducted to investigate the adverse effect of the exposure of this substance on the respiratory system (lungs) of male albino wistar rats. Twenty (20) albino wistar rats comprising of all males weighing between 150-230g were divided into four groups (A-D) of five animals each. Group A received only water, feed, and served as the control. Group B was exposed to dichlorvous inhalation 3hrs daily for a period of two weeks; Group C was exposed to dichlorvous inhalation 6hrs daily for a period of two weeks; while Group D was exposed to dichlorvous inhalation 10hrs daily for a period of two weeks. Twenty four hours after the last exposure, the animals were sacrificed by cervical dislocation and dissected. The lungs were weighed and fixed in 10% formal saline for histological studies. The body weight of the experimental groups decreased insignificantly when compared with the control group. The lungs weight increased significantly when compared to the control groups. Histological observation revealed a moderate to severe effects on the lungs with severe consolidated inflammatory exudates (discharge of fluids from pores), a moderate intra-alveoli hemorrhage, and a severe dilation of alveolar septa which is evident as emphysematous changes. This result revealed that the exposure to dichlorvous causes distortion of the normal histological architecture of the lungs. Thus, showing that dichlorvous inhalation influences the normal physiologic mechanisms of the lungs.

The experiment was conducted to investigate the comparative efficacy of indigenous medicinal plants, dadmardan (Cassia alata) and neem (Azadiracta indica) and ivermectin against skin lesions in calves and goats. Twelve calves of 8- 12 months and twelve goats of 1-2 years of age irrespective of sex having skin lesions (ringworm, scabies, humpsore, wounds) were used in the experiment. Selected calves and goats were divided into four equals groups (group A,BC and D), each group consists of 3 calves and 3goats. The group A kept as control group. The group B was treated with ivermectin (Cevamec 1%(R) @200 ug/kg body weight subcutaneously ,group C with dadmardan ointment (30%) ointment topically  and group D with 30% combined ointment(dadmardan and neem leaves) topically. Calves and goats treated with ivermectin were almost cured within18 days and the rate of healing was 98.36% & 99.03% respectively whereas animals treated with dadmardan ointment cured at 30thdays of treatment  in calves and at 27thdays of treatment in goats and  the rate of healing was 99.80% & 99.88%  respectively and those treated with  combined ointments of dadmardan and neem leaves cured at 27thdays of treatment  in calves and at 24th day of treatment in goats  and the rate of healing was 99.94% & 99.35% respectively. Ivermectin treatment was more effective in comparison to other treatments considering the time required for healing. On the other hand, treatment with the onitmemts of indigenous medicinals plants were more effective considering the rate of healing. It may be concluded that the ointments of indigenous medicinals plants (dadmardan ointment and the combined ointment of dadmardan and neem leaves) may be used as alternative drugs for the treatment of skin lesions in calves and goats.

Ameliorative Measure

In the search for medicinal plants that will provide ameliorative measure to patients with anaemic disorders. The methanol extract of O. gratissimum leaf was administered to Wistar rats for its effect on haematological profile. Twenty-eight (28) male Wistar rats ranging from 180-200g was randomly picked and placed into plastic cages labeled A-D. Group A served as the control group while groups B-D was the test groups. The  animals in group A was administered with distilled water orally by gavage. Group B were administered 50mg/ kg body weight of methanol extract of O. gratissimum, group C were administered with 100mg/kg bodyweight while group D were administered with 200mg/body of methanol extract of O. gratissimum for 14 days. Blood was collected from all the test rats and control by cardiac puncture using disposable syringe and needle then dispensed into tubes containing EDTA. The extract displayed a significant increase (p<0.05) in RBCs, Hb, PCV and platelet counts. More so, the  extract produced no significant (p>0.05)difference in MCV, MCH, MCHC and RDW WBC counts when compared with the normal control .Therefore, it will be logical to conclude that the extract of O. gratissimum might be a panacea in the management of anaemic conditions when properly harnessed due to its erythropoietic, haematopoietic and thrombopoietic effect. Keywords: Anaemia, erythropoietic, haematopoietic, thrombopoietic and phytochemicals.

We studied the effect of silymarin and dimercaptosuccinic acid (DMSA), a chelating agent that was administered individually or in combination against lead (Pb) toxicity in rats. Wistar rats (200 ± 20) were randomly divided into five groups. Group A served as a control. Groups B–E were exposed to 2000 ppm of lead acetate in drinking water for 8 weeks. Group B served as a positive control. Group C received silymarin (100 mg kg−1 orally) for 8 weeks. Group D received DMSA (75 mg kg−1 orally) once daily for the last 5 days of treatment. Group E received DMSA and silymarin as groups C and D, respectively. The effect of Pb was evaluated and accordingly the treatments on blood lead levels (BLLs), renal system, and genotoxic effects were calculated using comet assay. The BLLs were significantly increased following the exposition of lead acetate. The administration of silymarin and DMSA provided reduction in BLLs. Silymarin and DMSA provided significant protection on the genotoxic effect of Pb. The toxic effect of Pb on kidneys was also studied. Our data suggest that silymarin and DMSA improve the renal histopathological lesions.
