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.

Coronary heart disease (CHD) is the cause of 7,3 million death globally in 2008. The main pathophysiology process that leads to CHD is atherosclerosis which is caused by high LDL cholesterol level. The aim of this study was to explore bay leaf and celery leaf infusion effect on reducing LDL cholesterol level in dyslipidemic rat model. The type of this study was true experimental research using wistar rat (Rattus novergicus) as the sample. The rats were induced by high fat diet and PTU for two weeks then each of the group were given either bay leaf infusion, celery leaf infusion, simvastatin (positive control), or aquadest (negative control) for a week. The measurement of LDL level used Friedewald formulation. Data was analyzed using paired sample t test and one way ANOVA. As the result there was a significance reduction on LDL level after treatment with bay leaf (p=0,013) and celery leaf infusion (p=0,035) but there was no significance difference between groups (p=0,293). It was concluded that bay leaf and celery leaf infusion could reduce the LDL level in dyslipidemic wistar rat but there was no difference on the capability of the two different leafs on reducing LDL level.

Introduction: The prevalence of periodontitis has reached 42.8% in Indonesia. One contributing factor is Porphyromonas gingivalis. The ovarian dysfunction caused by ovariectomy procedures may also cause periodontitis. Post ovariectomy conditions resemble menopause, lowering the production of estrogen and progesterone hormones, leaving patients vulnerable to periodontitis. To prevent the side effects of the treatment, herbal ingredients are commonly used. The extract of cassava leaves is known to have pharmacological effects as an antioxidant and, thus, can be applied as a medicine for periodontitis.      Methods: A total of 21 rats were divided into three groups, (1) control: healthy rats; (2) Group P.1: P. gingivalis-induced rats; (3) Group P.2: ovariectomized rats. Groups P.1 and P.2 were further divided into three subgroups that were administered cassava leaves extract at a dosage of 179.2 mg/ kg BW, aquades and vitamin C. Rats were euthanized at day eight after the initial treatment to collect left mandibular first molar. The mandibular sections were immunohistochemically stained to quantify SOD expression using light microscope while the Image J software was used. Fibroblast cells expressing SOD are characterized by brown coloration in the cytoplasm and darker nucleus. Results: In periodontitis conditions, either due to P.gingivalis induction or ovarian dysfunction, fibroblast cells in rats given cassava leaves extract expressed higher SOD than rats given aquades, but still lower than rats given vitamin C. The result of the one way ANOVA test showed p value of 0,00, which means that there is a significant difference in all groups. Conclusion: Cassava leaves extract demonstrated the potential to increase the antioxidant expression in P. gingivalis-induced and ovarian dysfunction rats.

The Difference

Background: Pulp inflammation can be treated with pulp capping by calcium hydroxide as the gold standard. Pulp capping by calcium hydroxide could causing tissue necrosis followed by inflammation. Calcium hydroxide combined with propolis which have anti-inflammatory effects through inhibition of the Nf-kB pathway and pro-inflammatory cytokines. That process will inhibit the increase of vascular permeability and neutrophil chemotaxis. Inflammatory process can accelerate by controlling the amount of neutrophil cells as a acute phase marker, so the healing process occurs more quickly. Therefore it is necessary to study the amount of neutrophil cells in the pulp perforation of Wistar rats after applicated by combination of calcium hydroxide-propolis. Purpose: To analyze the difference amount of neutrophil cells on the Wistar rats pulp perforation after applicated by calcium hydroxide-propolis combination compared with calcium hydroxide-aquadest Method: M1 tooth perforated for all groups with three types tratment: no medication (control group), calcium hydroxide-aquadest 1: 1 (P-1 group), and calcium hydroxide-propolis 1: 1.5 (P-2 group) and closed with cention. Observations were made on the 1st, and 3rd day with HE staining. Results: One Way ANOVA shown a significant difference (p <0.05) of the average amount of neutrophil cells between all treatment groups on 1st day (p=0,000) and 3rd day (p=0,000). The amount of neutrophil cells in the calcium hydroxide-propolis (P-2) combination group was lower than control group and calcium hydroxide-aquadest (P-1) group on the 1st and 3rd day. Conclusion: The amount of neutrophil cells after application of calcium hydroxide-propolis is lower than calcium hydroxide-aquadest application.

Background: Periodontitis is an inflammatory disease of the periodontal tissues usually provoked by Actinobacillus actinomycetemcomitans (A. actinomycetemcomitans) bacteria. In the periodontitis healing process, macrophages play a significant role in the inflammatory stage. Brotowali (Tinospora crispa) consists of flavonoids that can stimulate periodontitis healing. Methods: Brotowali extract was derived from dried brotowali stems, processed into powder, and macerated with ethanol 80%. After that, the extraction was performed in three different concentrations, which were 25%, 50%, and 100%. five groups of Wistar rats were divided into Healthy wistar rats (control negative) Wistar rats suffering from periodontitis (control positive), Wistar rats suffering from periodontitis treated with 0.1 ml of 25% brotowali extract (treatment I), suffering from periodontitis treated with 0.1 ml of 50% brotowali extract (treatment II), and Wistar rats suffering from periodontitis treated with 0.1 ml of 100% brotowali extract (treatment III). The histological slide of each sample then was made to determine the number of macrophages cells. Results: One-Way ANOVA analysis revealed a notable difference among the groups. Tukey HSD Test (Post Hoc Test) showed no significant difference between (treatment group I) and (treatment group II). Conclusion: Brotowali extract may influence macrophage cells count of Wistar rats caused by A. actinomycetemcomitans bacteria.
