Abstract   Airway remodelling refers to the structural changes that occur in the airway wall in asthma.  These is  irreversible changes to the airway, with damage of bronchiolus epithelium because the  airway epithelium undergoes apoptosis  as one of its manifestations. Empirically black seed has been known as bronchial asthma therapy for many years ago. The purpose of the research is to test the effect of black seed (Nigella sativa L.) extract to apoptosis of bronchiolus epithelium and apoptosis of T lymphocytes the airway bronchial asthma on asthma mouse model. Female mice were used in the expeimental laboratory research and allergic mouse model was got by given ovalbumin twice within 3 weeks intraperitoneally and 3 times per week within 6 weeks by inhalation. Black seed extract is given in 3 different dose (0,024 cc/day, 0,048 cc/day and 0,096 cc/day) for 9 weeks. Sample was chosen randomly to share it within 5 group containing 6 mice in every group ; negative control group (without any treatment, n=6), positive control group (sensitizied with ovalbumin, n=6), JH1 group (sensitizied with ovalbumin and treating with first dose of black seed extract, n=6), JH2 group (sensitizied with ovalbumin and treating with second dose of black seed extract, n=6), JH3 group (sensitizied with ovalbumin and treating with third dose of black seed extract, n=6). The parametric that is used in this research is the change in the color of the nucleus of bronchiolus epithelium and T lymphocytes the airway bronchial asthma shown the occurrence of browning apoptosis. The result shown a significant increase of apoptosis of bronchiolus epithelium on  positive control group to compare with negative control group. The apoptosis of bronchiolus  epithelium on JH1 shown an increase compare with positive control group. For JH2 and JH3 groups shown a decrease the apoptosis of bronchial epithelium compare with positive control group. And the research indicate that the unsignificant aptosis decrease were happen on  a group with positive control instead of the group with negative control. Meanwhile, on JH1 group, apoptosis decrease were happening more significantly than the positive control group does, the aptosis increases were happen on JH2 and JH3 group, but its not capable to exceeding the positive control group apoptosis amount The conclusions is the black seed (Nigella sativa L.) extract can decrease apoptosis of bronchiolus epthelium on asthma mouse model in the third dose as the best result and the doses of black seed extract that were giving to the experiment mice can not increasing the apoptosis T Lymphocyte, thus requiring further research to figure out the perfect doses to increasing against respiratory tract apoptosis T Lymphocyte.   Keyword: asthma, black seed, the apoptosis of bronchiolus epithelium, apoptosis limfosit T.

OBJECTIVE: To evaluate the in vitro ionic degradation and slot base corrosion of metallic brackets subjected to brushing with dentifrices, through analysis of chemical composition by Energy Dispersive Spectroscopy (EDS) and qualitative analysis by Scanning Electron Microscopy (SEM). METHODS: Thirty eight brackets were selected and randomly divided into four experimental groups (n = 7). Two groups (n = 5) worked as positive and negative controls. Simulated orthodontic braces were assembled using 0.019 x 0.025-in stainless steel wires and elastomeric rings. The groups were divided according to surface treatment: G1 (Máxima Proteção Anticáries®); G2 (Total 12®); G3 (Sensitive®); G4 (Branqueador®); Positive control (artificial saliva) and Negative control (no treatment). Twenty eight brushing cycles were performed and evaluations were made before (T0) and after (T1) experiment. RESULTS: The Wilcoxon test showed no difference in ionic concentrations of titanium (Ti), chromium (Cr), iron (Fe) and nickel (Ni) between groups. G2 presented significant reduction (p < 0.05) in the concentration of aluminium ion (Al). Groups G3 and G4 presented significant increase (p < 0.05) in the concentration of aluminium ion. The SEM analysis showed increased characteristics indicative of corrosion on groups G2, G3 and G4. CONCLUSION: The EDS analysis revealed that control groups and G1 did not suffer alterations on the chemical composition. G2 presented degradation in the amount of Al ion. G3 and G4 suffered increase in the concentration of Al. The immersion in artificial saliva and the dentifrice Máxima Proteção Anticáries® did not alter the surface polishing. The dentifrices Total 12®, Sensitive® and Branqueador® altered the surface polishing.

Background: Dental infections were caused by the bacterium overgrowth on the surface of the tooth, and treatment should always be set up to prevent this development.Antibiotics have long been used as a conventional antibacterial medication, but their overuse has resulted in microbes gaining resistance to many of the antibiotics, trying to make many commercialized therapeutic remedies ineffectual and resulting to infection recurrence. In this regard we aim to analyze the antibacterial activity of nigella sativa seeds’ and fenugreek seed extract rinses against S. mutans' colonies. Methodology: It was a preclinical experimental study conducted at Baqai Medical and Dental College Karachi., from January - June 2021. Calculated sample size was n = 80 Consecutive sampling technique was used. Plaque of study participants was collected on sterile strips that was transported to laboratory for culture in sterile containers.The extract of Fenugreek seed and nigella sativa seed was kept in an airtight bottle and stored in a refrigerator till usage. The extracts were diluted in distilled water in 1:4 (Extract: Distilled water). Study participants were instructed to not brush their teeth before sampling. Study participants were divided into four groups (negative control, positive control, fenugreek seed extract group and Nigella sativa group) each group had 20 participants. Diluted Fenugreek seed extract and Nigella sativa extract was given to experimental groups for rinses. Results: There was significant decrease in number of colonies in positive controls, fenugreek seed extract group and nigella sativa extract group and there was no change in number of colonies in control group. Furthermore, the analysis showed significant (p-value = 0.001) difference among the groups followed by post hoc analysis. Post hoc analysis showed no difference between positive control, fenugreek seed extract group and nigella sativa group. Conclusion: Fenugreek seed extract and Nigella Sativa seed extract showed comparable antibacterial properties. Also, the effect was found to be similar to commercially available mouth rinse.

Aim: This study was aimed at investigating the effects of aqueous extracts of both Nigella sativa and Piper guineense on the liver enzymes; alanine amino transferase (ALT), aspartate amino transferase (AST) and alkaline phosphatase (ALP). Also the effect of Nigella sativa and Piper guineense extracts on the histology of the liver of Wistar rat was also studied. Materials and Methods: A total of twenty five Wistar rats were used for the study. The animals were grouped into five groups, each having five animals. They were induced with sucrose and margarine to cause high sugar levels and hyperlipidemia respectively except the positive control group which was fed normal feed. The groups were: the positive control group, the negative control group which were induced without treatment, the uziza leaf group which were induced and were treated with 2 ml of aqueous extract of uziza leaf, the black seed group which were induced and were treated with 2 ml of aqueous extract of black seed, and the black seed and uziza group which were induced and were treated with 2ml of aqueous extract of black seed and 2 ml of aqueous extract of uziza leaf.  Results: The result showed that the extracts decreased the ALT and AST and ALP activities in the rats in a time dependent manner with highest decrease obtained on the third week of treatment with the extracts.  The ALT activity (U/L) on the third week of treatment showed for the, negative control (64.48 ± 0.22), uziza leaf (28.82 ± 0.12), black seed (32.65 ± 0.02), black seed and uziza leaf (16.04 ± 0.02) (p≤0.05). The decrease in activity for AST levels (U/L) on the third week of treatment, showed for the negative control (58.00 ± 0.02), uziza leaf (11.00 ± 0.01), black seed (12.00 ± 0.02), black seed and uziza leaf (8.00 ± 0.02). Conclusion: It can be concluded that both uziza leaf and black seed have hepatoprotective effect on the liver.

Effects of GSE and vitamins C and E on aspirin- and ethanol-induced gastric ulcer and associated increases of lipid peroxidation in rats were compared. Two experiments were conducted. Rats were randomized into eight groups: a negative control and seven groups that received aspirin or ethanol for ulcer induction: one positive control (vehicle) and six with VC, VE, or GSE (25 and 250 mg/kg). Ulcer indexes and gastric levels of malondialdehyde (MDA) were quantified. VC, VE, and GSE (25 and 250 mg/kg) decreased aspirin, and ethanol-induced ulcers and MDA values compared with positive control group. The magnitude of aspirin ulcer reduction was comparable for all treatments, and MDA decrease with GSE was higher than with VC and tended to be greater, albeit none significantly, than with VE. GSE was more effective than VC and VE for lowering the ethanol ulcers, while the decrease of MDA levels with GSE was greater than with VC, but comparable to that achieved with VE. GSE protected against ethanol-induced gastric ulcers more effectively than VC or VE, while its protection against aspirin ulcers was comparable for all treatments. GSE produced the greatest reductions of gastric MDA in both models.

Objective:  The aim of this study is to investigate the protective effects of methanolic extract of Nigella sativa (MENS) (Black seed) against cardiotoxicity of cadmium in albino rats.  Methods: Twenty five (25) male albino rats, weighing (150-170g), were randomly grouped into five groups: A-E. Group B (Negative Control) received intraperitoneal administration of cadmium chloride (CdCl2, 5mg/kg) only, group C received CdCl2 and low dose MENS (300mg/kg, oral), group D received CdCl2 and high dose MENS (600mg/kg, oral), group E (Positive control) received CdCl2 and Vitamin C (200mg/kg, oral), for 7 days. No treatment was administered to group A (Normal control). Cardiac injury was assessed by measuring serum levels of Aspartate aminotransferase (AST), Lactate dehydrogenase (LDH) and Creatine kinase (CK-MB) using standard methods. The heart was harvested for histopathological examination. Results: CdCl2 induced significant cardiotoxicity with marked elevation in the levels of biochemical markers of cardiac functions (p<0.05 or p<0.01); these were however attenuated by MENS. Histopathological examination of the heart sections supported the biochemical findings. Conclusion: Nigella sativa seed extract is potentially cardioprotective against harmful chemical toxins such as cadmium. Keywords: Cadmium, CdCl2, Nigella sativa, Medicinal food, cardiotoxicity

Abstract Objective: This study investigated the effect of the condition of lubrication on the friction between brackets and NiTi archwires of different rounded cross-sections. Methods: Brackets (Roth, GAC) were affixed to a device connected to a universal testing machine into which segments of archwire were placed (NiTi, Nitinol, GAC) with cross-sections of 0.012-in, 0.016-in and 0.020-in. Once the wire was in the bracket slot, the following lubricants were applied: human saliva (HS: positive control), distilled water (DI), mucin-based (MUC) or carboxymethylcellulose-based (CMC) artificial saliva. In the negative control group, no lubricant was used. The combination between the wire cross-sections and the lubrication condition generated 15 groups with 15 samples each. Data were submitted to two-way analysis of variance and Tukey’s test. Results: There was no significant interaction between the wire cross-section and the condition of lubrication (p= 0.901). Irrespective of whether lubricants were used or not, there was a significant increase in friction with an increase in the cross-section of the wire (p< 0.001). For any wire, the group tested in the presence of MUC was not different from that in which HS was applied. On the other hand, when the application of lubricants was suppressed, significantly higher friction values were observed. The CMC group and the DI group demonstrated intermediate behavior. Conclusions: Friction increased with the increase of the cross-section of the NiTi archwire, but regardless of the archwire, friction with MUC artificial saliva was similar to that of HS and lower than in dry conditions.

This study investigated the hepatoprotective effect of methanol seed extract of Citrus tangerina on liver damage induced by paracetamol in laboratory rats. Wistar rats were used in this study and categorized into five groups. Groups 1 and 2 received 10 ml/kg normal saline orally, groups 3 and 4 were administered 200 mg/kg and 400 mg/kg respectively of Citrus tangerina seed extract orally, while silymarin 100 mg/kg served as standard drug treatment for group 5. Following six (6) days of pretreatment with the extract, hepatotoxicity was induced with paracetamol 3 g/kg (orally) in all the groups except the positive control group. At the end of the experiment (24 hours after induction), blood samples were collected under diethyl ether anaesthesia for biochemical markers of liver enzymes and antioxidative stress and the liver was harvested for histopathological studies. Both doses (200 mg/kg and 400 mg/kg) of Citrus tangerina seed extract significantly (p < 0.05) reduced the liver enzymes level, but significantly (p < 0.05) increased antioxidant enzymes when compared with the negative control group. Liver histology showed that the Citrus tangerina seed extract prevented hepatic injury induced by paracetamol. The methanol seed extract of Citrus tangerina possesses antioxidative and hepatoprotective effects.

Background: Plant derived medicines are widely used in traditional culture all over the world. Objectives: To determine the effect of Celery Seed Extract (CSE) on uric acid levels in hyperuricemic rats and to compare the effect of allopurinol and CSE. Methods: It was an animal experimental research study. Group A served as negative control whereas Group B served as positive control. CSE was given orally to three groups of rats (C, D, and E). One hour prior to administration of CSE; potassium oxonate was injected intraperitoneally in all groups except negative control to induce hyperuricemia. Similarly, group F was given allopurinol one hour after injection of potassium oxonate. Blood samples were collected for uric acid estimation. Results: It was found that administration of both CSE (group C, D, E) and allopurinol (group F) significantly lowered serum uric acid levels (p<0.001) as compared to positive control (group B). Serum uric acid lowering effect of both drugs CSE and allopurinol was found to be statistically significant on day 3rd and day 7th and was almost comparable. Conclusions: Celery seed extract significantly reduces serum uric acid levels in potassium oxonate-induced hyperuricemic rats and its uric acid lowering effect was comparable with that of allopurinol.
