Effect of Cymbopogon olivieri-based herbal vaginal product on bacterial vaginosis.

OBJECTIVE: Bacterial vaginosis is the most common vaginal infection in reproductive-age women. If it is not treated, the quality of life will be reduced. In this study, the herbal medicine product Cymbopogon olivieri was used for its treatment. METHODS: This study was conducted with 90 women. The patients were randomly divided into two groups of 45: Cymbopogon olivieri and metronidazole. The treatment period was 7 days for each group. Improvement status was determined by eliminating at least three out of four of Amsel's criteria. A new variable with two order levels (negative and positive) was constructed. This new variable shows the status of the treatment process. Chi-square and Fisher's exact tests were used to examine the relationship between the new variable and treatment status. RESULTS: The results demonstrate that Cymbopogon olivieri and metronidazole significantly reduced the burning, itching, malodor, abnormal vaginal discharge, pH, clue cell, and positive whiff test (p<0.05). The findings also demonstrate that neither treatment was statistically different from the other for at least three of Amsel's criteria. CONCLUSION: This study shows that the effect of Cymbopogon olivieri on bacterial vaginosis is similar to that of metronidazole. Hence, Cymbopogon olivieri is a suitable option to treat bacterial vaginosis.

Eosinophils and chronic obstructive pulmonary diseases (COPD) in hospitalized COVID-19 patients.

BACKGROUND: The emergence of coronavirus disease 2019 (COVID-19) as a global health emergency necessitates continued investigation of the disease progression. This study investigated the relationship between eosinophilia and the severity of COVID-19 in chronic obstructive pulmonary disease (COPD) patients. METHODS: This cross-sectional study was conducted on 73 COPD patients infected by COVID-19 in Afzalipour Hospital, Iran. Peripheral blood samples were collected for hematological parameter testing, including eosinophil percentage, using Giemsa staining. Eosinophilia was defined as≥ 2% and non-eosinophilia as< 2%. The severity of pulmonary involvement was determined based on chest CT severity score (CT-SS) (based on the degree of involvement of the lung lobes, 0%: 0 points, 1-25%: 1 point, 26-50%: 2 points, 51-75%: 3 points, and 76-100%: 4 points). The CT-SS was the sum of the scores of the five lobes (range 0-20). RESULTS: The average age of patients was 67.90±13.71 years, and most were male (54.8%). Non-eosinophilic COPD patients were associated with more severe COVID-19 (P= 0.01) and lower oxygen saturation (P= 0.001). In addition, the study revealed a significant difference in the chest CT severity score (CT-SS) between non-eosinophilic (9.76±0.7) and eosinophilic COPD patients (6.26±0.63) (P< 0.001). Although non-eosinophilic COPD patients had a higher mortality rate, this difference was not statistically significant (P= 0.16). CONCLUSIONS: Our study demonstrated that reduced peripheral blood eosinophil levels in COPD patients with COVID-19 correlate with unfavorable outcomes. Understanding this association can help us identify high-risk COPD patients and take appropriate management strategies to improve their prognosis.

The expression of HER2/neu in patients with lung cancer and its associated factors.

BACKGROUND AND OBJECTIVES: Lung cancer is the most common cause of cancer-related death worldwide in both sexes. Evidence suggests the role of genetic factors in lung cancer. Studying of such factors can help understand the cancer prognosis. Overexpression of the human epidermal growth factor receptor-2 (HER2/neu) protein is considered an important prognostic factor in breast cancer, but its role has not been confirmed in lung cancer. Therefore, the present study aimed to investigate the role of its expression in patients with lung cancer. MATERIALS AND METHODS: In this cross-sectional study, patients aged >18 years who were referred to Afzalipoor Hospital, Kerman, Iran, from 2016 to 2017, and were diagnosed with lung cancer were enrolled into the study if they had a pathological sample of their cancerous lung. Their demographics were recorded, and the sample was sectioned and stained to measure HER2/neu gene expression according to DAKO instructions using heat-induced antigen retrieval (HIER) enzyme marker. RESULTS: The samples of 100 patients with lung cancer were evaluated (84% men and 16% women) with a mean age of 61.34 years (standard deviation of 12.51 years). HER2/neu expression was significantly associated with the type of cancer and was highest in adenocarcinoma and zero in small cell carcinoma (P < 0.001), but not with patients' sex, age, smoking status and family history of cancer (P > 0.05). CONCLUSION: These results emphasized the overexpression of HER2/neu in different types of lung cancer, which can be used further for therapeutic purposes. The results showed that HER2/neu was overexpressed not only in adenocarcinoma but also in other types, like squamous cell carcinoma. Therefore, all subtypes of non-small cell lung carcinoma should be considered for anti-HER2 therapies, and further research is required for small cell lung carcinoma.

The effect of combining basil seeds and gum Arabic on the healing process of experimental acetic acid-induced ulcerative colitis in rats.

Background & aim: Ulcerative colitis (UC) is a chronic recurrent inflammatory disease of the large intestine and rectum that oxidative stress and severe inflammation are the main features of this disease. Previous studies have shown that separate consumption of basil and gum arabic can reduce inflammation and oxidative stress. The aim of the study was evaluating the effect of treatment with basil seeds given together with gum arabic on healing, inflammation and oxidative stress in the course of experimental colitis in rats. Experimental procedure: A total number of 50 male rats were used, randomly assigned to five groups of 10 rats each. Colitis was induced in rats by enemas with 4% solution od acetic acid. Four days after induction of colitis, rats were treated for next 4 days with saline or combination of basil seeds plus gum arabic (1 mg/kg) or sulfasalazine (100 mg/g) rectally. The experiment was terminated after last dose of treatment. Rats without induction of colitis were used as a sham group. Results: Acetic acid-induced colitis increased the macroscopic and histopathological damage scores of the colon as well as colon levels of MDA(Malondialdehyde), MPO(Myeloperoxidase), TNFα(Tissue necrosis factor α), IL6 (Interleukin 6)and IL17(Interleukin 17) and decreased SOD(Superoxide Dismutase), GPx (Glutathione Peroxidase) and IL10 (Interleukin 10) levels compared with the control group(P < 0.001). Treatment with basil and gum arabic reduced macroscopic and histopathological damage scores (P < 0.01) of the colon, MDA, MPO, TNFα, IL6(P < 0.001) and IL17 (P < 0.01) levels of the colon and increased SOD, GPx and IL10 levels compared to the colitis group (P < 0.01). Conclusion: Rectal administration of combination of basil seeds plus gum arabic after induction of colitis, exhibits antioxidant and anti-inflammatory effects, and accelerates the healing of the colon in experimental colitis evoked by acetic acid.
