    Appraisal of oral lesions status of HIV/AIDS patients in South Western Uganda
    (Brazilian Journal of Oral Sciences, 2008) Agwu, Ezera; Ihongbe, John C.; Tirwomwe, Jackson F.; Pazos, Victoria; Tirwomwe, Michael; Casadesus, Luis
    Aim: To establish a regional surveillance data that may contribute to improvement of oral health prevention/control programs in South Western Uganda. Methods: Using WHO guidelines, HIV-associated oral lesions were identified among 605 HIV/AIDS patients (469 females and 136 males), selected at random from 4 districts of South Western Uganda. Pearson’s Chi square test of independence (α=0.01), was used to compare results. Results: Prevalence of oral lesions was 73.2%. Pseudomembranous Candidiasis (PC) showed the highest overall prevalence of 71.1% (34.9% single and 36.2% mixed); followed by 39.9% prevalence of Erythematous Candidiasis (EC) (13.2%) single; 26.7% mixed) and 18.8% prevalence of Angular Chelitis (AC) (3.1% single and 15.7% mixed). There was: 23.6% co-infection of PC and EC; 12.6% PC and AC, 3.1% were EC and AC, and 17.0% intra-oral pigmentation. Prevalence of oral lesions was significantly (p<0.01) dependent on host pre-exposure to antimicrobials. Conclusions: Oral infections are still highly prevalent among the studied HIV/AIDS patients in South Western Uganda. This observation may be due to inadequate antimicrobial agents and oral/dental care. There’s urgent need to train primary health care workers in management of oral lesions associated with HIV/AIDS. More studies are needed to evaluate HIV/AIDS oral lesions in the populace.

    Hypoglycemic and High Dosage Effects of Bidens pilosa in Type-1 Diabetes Mellitus
    (Journal of Diabetes Mellitus, 2015) Ajagun-Ogunleye, Mulkah O.; Tirwomwe, Michael; Mitak, Ruth Nyaboke; Kasozi, Keneth Iceland; Mbiydzenyuy, Elvis Ngala
    Ethno-pharmaceutical products have received a lot of international attention in the scientific com- munity in the management of diabetes mellitus (DM). In this study we determined the anti-dia- betic and high dosage effects of Bidens pliosa in type 1 DM (T1DM). Methodology: Thirty rats were divided into six groups and subgrouped into the extract and non extract treatment groups. The extract treated group was subdivided into three groups which received 200 mg/kg, 400 mg/ kg and 800 mg/kg dosage treatments respectively. The blood glucose levels were monitored using a standard glucometer for one month, and biochemical analysis of the two liver function enzymes; Alanine aminotransferase (ALT) and Aspartate aminotransferase (AST) were carried out at the Institute of Biomedical Research (IBR-KIU-WC) at the end of week IV. The study revealed that Bidens pilosa maintained hypoglycemia for a period of two weeks and this status was lost in subsequent weeks. T1DM rats treated with a dosage of 200 mg/kg showed a better recovery (355.25 - 164.5 mg/dl) of the glucose levels, followed by those that were being treated at 400 mg/kg. The AST and ALT enzymes in blood varied with a mean ± SEM (33.72 ± 32.32 to −7.23 ± 12.61 IU and 22.98 ± 11.12 to 42 ± 38.2 IU, respectively) in both the glibencimide® and in the 800 mg/ kg treatment groups in the study. High dosages of extract were associated (P = 0.049) with increased systemic enzyme leakage. In conclusion, tissue degeneration caused by high levels of the extract was accompanied by leakage of various enzymes (AST and ALT) into the blood, which could be a major etiological factor for the development of secondary systemic pathologies, thus potentially worsening the effects of an existing T1DM prognosis in human patients. The preliminary results indicate that a dose of Bidens pilosa has an anti-diabetic effect for a limited initial duration before starting to cause systemic toxicological effects. It is highly recommended that further investigation into the cellular mechanisms and consequences of any therapy involving Bidens pilosa be carried out.

    Hypoglycemic and Toxic Effect of Morus mesozygia Leaf Extract on the Liver and Kidneys of Alloxan-Induced Hyperglycemic Wistar Rats

    Diabetes mellitus (DM) is one of the leading causes of mortality and morbidity in developed and developing countries. DM is characterized by increased levels of glucose that eventually progress to frequent urination, increased thirst, and increased hunger [1]. According to global estimates of diabetes, in 2013, 382 million people had diabetes; this number is however expected to rise to 592 million by 2035. Majority of the people with diabetes live in low- and middle-income countries and these will experience the greatest increase in cases of diabetes over the next 22 years [2]. In Africa alone, about 12.1 million people lived with diabetes mellitus by 2010 [3, 4], and according to research, there will be an expected increment in the prevalence of DM in Asia and Africa by 2030. )is is because of increased urbanization and lifestyle changes that have changed the indigenous diet to a modern diet [5].
