This study focuses on the anti-protozoan activities of Stachytarpheta angustifolia (Tarkajiya; Hausa, Devil’s coach whip; English) on haematological parameters of Albino Wistar rats which is an unexplored study area. The work is aimed at the determination of the effects of S. angustifolia on Wistar Rats, when exposed to herbal extract on the haematological parameters of Wistar Rats infected with E. tenella Biomarkers. The plant was obtained whole; dried under the shade, made into a powdered form and aqueous extraction method carried by maceration technique. After infecting the experimental animals with the parasites; E. tenella, the following respective doses of 750 mg and 1500 mg were administered to the rats in groups of 3 and 4. Results obtained were analyzed using Analysis of Variance (ANOVA). It was discovered that no significant harmful effect on the rats was recorded, but 60 % of the parasites were killed. This work demonstrated that the herbal extract killed the parasites but induced minimal stress to the animals as shown by the low haematological parameters in the study.

Metabolic processes were investigated in plasma and erythrocytes of Wistar rats exposed to daily 10-min sessions of NO inhalation for 30 days. These included determination of glucose and lactate, catalase activity, and activities of aldehyde dehydrogenase (ALDH), lactate dehydrogenase (LDH), and catalase. NO inhalation in a concentration of 20 ppm, 50 ppm and 100 ppm caused an increase in glucose and lactate. Inhalation of 100 ppm NO also increased catalase activity. Inhalation of all NO concentrations resulted in a decrease of ALDH activity, while the decrease in LDH activity was observed at NO concentrations of 50-100 ppm

Wound examination is indispensable in forensic practice. The scientific field of wound age determination has advanced progressively during recent years.The purpose of this study was to determine the differences of fibronectin and TGF-β1 expression in both antemortem and postmortem wounds. This study was an experimental with completely randomized design.  The skin wounds (vital and postmortem) were taken from fourty Wistar rats and divided into 10 groups of rats. Immunohistochemical staining was performed to determine the differences between antemortem and postmortem wounds. The result showed that in 30 minutes after antemortem wound infliction, all of samples showed weak reactivity for fibronectin and TGF-β1 (100%).  In first hour after wound infliction, 3 samples (75%) showed weakly positive and 1 sample (25%) strongly positive for fibronectin and TGF-β1.  In 2 hour after wound infliction, 1 sample (25%) showed weakly positive and 3 sample (75%) strongly positive for fibronectin and TGF-β1.  In 3 and 4 hour after wound infliction, all of samples strongly positive for fibronectin and TGF-β1.  In postmortem wound, all of samples showed negativity for fibronectin and TGF-β1. In conclusion, fibronectin and TGF-β1 may be useful in the determination of wound vitality. Keywords: wound, fibronectin, TGF-β1, vitality
