Lead is a heavy metal found in earth’s crust. It is a widespread and insidious environmental toxin known as a severe and aggressive contaminant to human and animal organisms’ health status. This work is aimed at evaluating the effect of aqueous extract of Ocimum gratissimum (OG) on lead induced changes in the thymus of adult albino wistar rats. Thirty five male Wistar rats were used in the study and were randomly divided into seven groups with five rats in each group. The rats in Group one (G1) served as the Control and received distilled water. Group 2 received 120 mg/kg body weight (bwt) of lead acetate, G3 received 375 mg/kg bwt of OG only. G4 received 120 mg/kg bwt of lead acetate and OG extract at 375 mg/kg bwt., G5 received 120 mg/kg bwt of lead and OG at 750 mg/kg bwt. G6 received 375 mg/kg bwt of OG in two weeks followed by 120 mg/kg bwt of lead acetate for one week, while G7 received 120 mg/kg bwt of lead acetate and Vitamin C at 11900 mg/kg. All the administrations were carried out orally for twenty one (21) days. At the end of the administration, the rats were fasted for 24 hours. They weighted and humanely sacrificed via cervical dislocation. The thymus were harvested in all the groups and prepared for histological studies using routine haematoxylin and eosin (H&E) staining techniques. The result of the present study shows that lead possessed a distortive effect in the histoarchitecture of thymus of the wistar rat in G2 when compared with G1. Treatment of these experimental animals with vitamin C prove to posses more ameliorative effect in restoring the histoarchitecture on lead toxicity in the thymus closed to normal than OG. Therefore, it is suggested that aqueous extract OG can act via the same pathway as vitamin C, in maintaining the normal histological structures of the thymus of adult albino wistar rat exposed to lead toxicity.

The present study evaluated the ameliorative effect of vitamin C on alteration in thyroid hormones induced by low-dose subchronic coadministration of chlorpyrifos (CPF) and lead (Pb). Forty Wistar rats were divided into 4 groups of 10 animals each. Groups I and II were administered soya oil (2 mL/kg) and vitamin C (100 mg/kg), respectively. Group III was coadministered CPF (4.25 mg/kg ~1/20th LD50) and Pb (250 mg/kg ~1/20th LD50), respectively. Group IV was pretreated with vitamin C (100 mg/kg) and then coadministered with CPF (4.25 mg/kg) and Pb (250 mg/kg), 30 min later. The regimens were administered by gavage for a period of 9 weeks. The marginal decrease in serum triiodothyronine and thyroxine and the significant increase in the concentrations of thyroid stimulating hormone and malonaldehyde in the group coadministered with CPF and Pb were ameliorated by vitamin C partly due to its antioxidant properties.

AbstrakPaparan timbal asetat dapat menyebabkan kerusakan sel hati dan menurunkan aktivitas enzim yang bekerja sebagai antioksidan esensial dalam tubuh. Vitamin C merupakan senyawa alami yang bersifat antioksidan kuat dan pengikat radikal bebas.Tujuan penelitian ini adalah menentukan efek pemberian vitamin C terhadap gambaran histopatologi hati tikus wistar yang terpapar plumbum asetat dan dilakukan di laboratorium Fakultas Farmasi dan laboratorium Patologi Anatomi Fakultas Kedokteran Universitas Andalas. Penelitian ini dilakukan pada 28 ekor tikus wistar jantan, berumur 3 bulan, berat badan ± 200 gr. Didapatkan bahwa pada pemaparan timbal 50 mg/kgBB/hari selama 4 minggu meningkatkan skor Manja Roenigk hati tikus wistar. Penambahan vitamin C 50 mg/kgBB/hari dan 75 mg/kgBB/hari pada tikus yang terpapar timbal asetat menunjukkan penurunan skor Manja Roenigk pada hati tikus wistar. Berdasarkan uji t berpasangan ternyata tidak terdapat perbedaan yang signifikan antara skor Manja Roenigk yang tidak terpapar dan terpapar timbal asetat (p = 0,501). Berdasarkan uji one way Anova terdapat pengaruh yang signifikan vitamin C terhadap gambaran histopatologi hati tikus wistar (p = 0,000). Secara statistik pemberian kedua dosis vitamin C ini tidak memberikan perbedaan yang bermakna (p = 0.379).Kesimpulan penelitian ini adalah terdapat pengaruh proteksi vitamin C terhadap mikroskopis hati tikus wistar yang telah terpapar timbal asetat.Kata kunci: Timbal Asetat, Gambaran Histopatologi Hati, Vitamin C, Plumbum Asetat, Manja Roenigk AbstractExposure of lead acetate can caused cell injury in liver and decrease activity of enzyme which works as essential antioxidant in body. Vitamin C is a natural compound as potent antioxidant and free radical binding.The objective of this study was to determine the effect of vitamin C on liver histopathology in exposed lead acetate wistar rats. This research was conducted at Pharmacy Laboratory and Pathology laboratory, Faculty of Medicine, Andalas University. The study performed on 28 male Wistar rats, 3 months old, body weight 200 g.             It was found that 50 mg/ kgBW/day of lead exposure for 4 weeks increased Manja Roenigk’s grading of wistar rat’s liver. Administration of vitamin C 50 mg/kgBW/day and 75 mg/kgBB/day to rat which exposed to lead acetate showed decrease in score of Manja Roenigk on wistar rat’s liver. Based on paired sample t test was not significant difference score of Manja Roenigk between unexposed and exposed lead acetate (p = 0.501). Based on one way Anova test was found  a significant effect of vitamin C to histopathology of wistar rat’s liver (p = 0.000). Statistically administration of both dose vitamin C did not give significant difference (p = 0.379).The conclusion of this study show  there is the effect of protection from administration of vitamin C to microscopic Wistar rat liver which exposed to lead acetateKeywords: lead acetate, histopathology of liver, vitamin C, plumbum acetate, Manja Roenigk
