Background Rhinosinusitis is a common disorder and its treatment includes a variety of topical and systemic drugs. This study was designed to determine the histopathological effect of thymoquinone on experimentally induced rhinosinusitis in rats. Methods Sixty rats were randomly allocated into 3 test and 2 control groups, each of which consisted of 12 animals. The rhinosinusitis model was induced using intranasal application of platelet-activating factor. In test groups, the animals were separated into groups: (1) rhinosinusitis-antibiotherapy, (2) rhinosinusitis-thymoquinone, (3) rhinosinusitis-combination therapy. The positive and negative control groups were defined: rhinosinusitis group without any treatment and the group without rhinosinusitis, respectively. The histopathological features (vascular congestion, inflammation, and epithelial injury) in nasal respiratory and olfactory mucosa of animals were examined and graded according to their severity. A quantitative and statistical analysis of histopathological features was performed. Results All histopathological features showed statistically significant differences between negative and positive control groups, respectively. Conversely, neither the group with rhinosinusitis-antibiotherapy nor the group with rhinosinusitis-thymoquinone had a statistically significant difference with the negative control group. Moreover, none of the histopathological features showed a statistically significant difference, when the group with rhinosinusitis-antibiotherapy and the group with rhinosinusitis-thymoquinone were compared. A statistically significant difference was not determined when the group with rhinosinusitis-combination therapy was compared with the group with rhinosinusitis-thymoquinone. The histopathological features did not show a statistically significant difference between the group with combination therapy and the negative control Conclusion Thymoquinone is a promising bioactive agent for the treatment of rhinosinusitis, and its histopathological effect is as equivalent as an antibiotic.

Insulin resistance, which precedes type 2 diabetes mellitus (T2DM), is a widespread pathology associated with the metabolic syndrome, myocardial ischemia, and hypertension. Finding an adequate treatment for this pathology is an important goal in medicine. The purpose of the present research was to investigate the effect of an extract from Aloe vera gel containing a high concentration of polyphenols on experimentally induced insulin resistance in mice. A polyphenol-rich Aloe vera extract (350 mg/kg) with known concentrations of aloin (181.7 mg/g) and aloe-emodin (3.6 mg/g) was administered orally for a period of 4 weeks to insulin resistant ICR mice. Pioglitazone (50 mg/kg) and bi-distilled water were used as positive and negative controls respectively. Body weight, food intake, and plasma concentrations of insulin and glucose were measured and insulin tolerance tests were performed. The insulin resistance value was calculated using the homeostasis model assessment for insulin resistance (HOMA-IR) formula. Results showed that the polyphenol-rich extract from Aloe vera was able to decrease significantly both body weight ( p < 0.008) and blood glucose levels ( p < 0.005) and to protect animals against unfavorable results on HOMA-IR, which was observed in the negative control group. The highest glucose levels during the insulin tolerance curve test were in the negative control group when compared to the Aloe vera extract and pioglitazone treated mice ( p < 0.05). In conclusion, Aloe vera gel could be effective for the control of insulin resistance.

The aim of this study was to evaluate the sealing ability of three different canal filling techniques. Sixty-four roots of extracted human maxillary anterior teeth were prepared using ProTaper® rotary instruments. The specimens were then randomly divided into 3 experimental groups (n=16) and 2 control groups (n=8). The root canals were filled using cold lateral compaction (CLC group), continuous wave condensation technique using the Elements Obturation Unit® (EOU group), and ProTaper obturators (PT group). For the negative control group, 8 roots were filled using lateral compaction as in the CLC group, and the teeth were covered twice with a layer of nail varnish (NCG group). Another 8 roots were filled using lateral compaction, but without sealer, and these were used as the positive control (PCG group). A glucose leakage model was used for quantitative evaluation of microleakage for 24 hours and 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12 weeks. No significant difference in the cumulative amount of leakage was found between the three experimental groups at all observation times. The lateral condensation of cold gutta-percha can guarantee a similar seal of canal fillings as can be achieved by using thermal methods, in the round canals.

Aim. The study aimed at evaluating the incidence of dentinal defects after root canal retreatment with ProTaper Universal retreatment (PTUR) and XP-endo Shaper and Finisher R (XP). Materials and Methods. Sixty extracted single-rooted human premolars were selected and divided into 4 groups of 15 teeth each. In the negative control group, the teeth were left unprepared. In the positive control group, the teeth were prepared with ProTaper Next and obturated with no further retreatment. In the PTUR and XP groups, the teeth were prepared and obturated followed by removal of the filling material at body temperature using PTUR and XP instruments, respectively. The roots were then sectioned at 3, 6, and 9 mm from the apex and observed under a digital microscope to detect defects. Results. PTUR group showed significantly higher ( p value <0.05) incidence of defects than the other groups. Comparison of no defects versus defects between groups in different areas of root canals demonstrated significant difference among the groups in the apical and cervical regions. Conclusion. Within the limitations of the present study, PTUR files created significantly more dentinal defects than XP files, with most of those defects at the cervical and apical areas of the root canals.

This study aim was to determine the influence ant nest plant extract (Myrmecodia pendans) on histopathological changeof white rat liver (Rattus novergicus) due to induced with paracetamol toxic dose. This study used 24 male white rats, divided into four groups, negative control group (P0) given placebo, positive control group (P1) given paracetamol dose 250 mg / kg bw for 10 days, P2 given ant nest extract 250 mg / kg bw and paracetamol dose 250 mg / kg bw for 10 days, P3 given ants nest extract 250 mg / kg bw for seven days, then continued by giving paracetamol and ants nest extract with dose 250 mg / kg bw for ten days. After the treatment done, all the rats were dinecropsed. Liver organs were taken and processed for making histopathology preparations. Parameters examined included hemorrhage, congestion, degeneration and necrosis. The data obtained were analyzed statistically by using Kruskal Wallis test followed by Mann Whitney test. Mann Whitney test results for all categories of histopathologic changes in  hemorrhagic, congestion, degeneration, and necrosis between negative control group (P0) and positive control group (P1) were significantly different (P <0.05), between negative control (P0) with P2 and P3 there was no significant difference (P> 0,05). Afterward, between the positive control (P1) and P2 with P3 there was a significant difference (P <0.05). I can be concludedthat the administration of paracetamol dose 250 mg/kg bw for 10 days affects the histopathologic changes of white rat liver. The administration of ant nest plant extracts can reduce the side effects of toxic doses of paracetamol.

Objective: Malaria infection remains a global concern due to increasing resistance to artemisinin-based combination therapy. This study examinedthe antimalarial effects of propolis extract alone and in combination with pasak bumi root extract.Methods: In the study, 30 mice were divided into six groups including two control groups, two groups of mice treated with propolis aloneat concentrations of 90 and 180 mg/kg body weight (BW), and two combination groups of mice treated with 90 or 180 mg/kg BW propolis incombination with 60 or 75 mg/kg BW pasak bumi, respectively. Plasmodium berghei 2% was injected into each mouse, and blood smears wereprepared after 8 days to assess parasitemia.Results: The results revealed no significant difference in parasitemia levels between the positive control and the two combination groups (p=0.136 and0.289, respectively). However, superior growth inhibition (GI) results were observed in the combination groups (97.97% and 97.83%, respectively)than in the propolis monotherapy groups, whereas better outcomes were observed in the positive control group (98.63% GI) than in the propolismonotherapy groups (23.88% and 51.66%, respectively).Conclusion: These results illustrate that combination therapy is superior to propolis monotherapy in inhibiting parasitemia.

Background: Transplacental congenital malaria is a vertical transplacental transmission of malaria parasites from the mother to the baby in utero or perinatally during labor. Cord blood that conveyed oxygen and nutrients from mother to fetus and return with carbon dioxide and other waste materials can transmit malaria pathogen. This study is aim to establish early diagnosis of transplacental congenital malaria using cord blood biochemical and haematological indices. Cord blood from 164 babies delivered at three hospitals in Kogi State between January and December, 2020 were microscopically investigated for malaria parasite. Biochemical and Haematological analyses were done using SYSMEX XP 300, Roche 9180 and VIS Spectrophotometer model 721. The data obtained were expressed as mean plus or minus standard deviation using SPSS 23. The indicator level of statistical significance was set at p<0.05. The results showed significant (p<0.05) decreased in values of WBC, platelet, sodium, potassium, urea, creatinine, RBC, PCV, haemoglobin and MCHC in malaria infected cord blood in comparison to malaria negative control group. Significant (P<0.05) increased activities of liver enzymes (AST, ALT, ALP), total protein, bicarbonate and chloride in malaria infected cord blood when compared with malaria negative group. However, no statistically significant difference in lymphocyte, MCV, MCH, neutrophil and mixed of both malaria infected and malaria negative cord blood. This study suggests that cord blood biochemical and haematological indices can be used to diagnose and manage transplacental congenital malaria in fetus and neonates. Keywords: Transplacental, Biochemical, Haematological and Congenital Malaria.
