The objective was to estimate the prevalence of intestinal protozoa among the aborigines and to determine the problems regarding the infection. The study was carried out in January 2006 in Pos Senderut, Pahang, Malaysia. Samples of faeces were collected from children and adults and these were fixed in PVA and trichrome staining was carried out. From the 130 individuals studied, 94 (72.3%) were positive with at least one intestinal protozoa. Nine intestinal protozoa namely Blastocystis hominis, Giardia lamblia, Entamoeba histolytica, Entamoeba coli, Endolimax nana, Entamoeba hartmani, Entamoeba polecki, Iodamoeba butschlii and Chilomastix mesnili were detected. The prevalent species were B. hominis (52.3%), followed by G. lamblia (29.2%), E. coli (26.2%) and E. histolytica (18.5%). The other species ranged from 1.5 to 10.8%. Among the positive samples, mixed infection with E. histolytica and G. lamblia was 3.8%, E. histolytica and B. hominis was 15.4%, G. lamblia and B. hominis was 17.7%. Triple infection of E. histolytica, G. lamblia and B. hominis was 3.1%. The infection was more prevalent in children below 10 years age group (45.4%) and lowest in the age above 60 years (3.8%). The high prevalence was attributable to poor environmental management, poor personal hygiene and lack of health education.

We performed DNA analysis on cord blood samples of 128 Chinese male neonates diagnosed as G6PD deficiency in Hospital Universiti Kebangsaan Malaysia by a combination PCR-restriction enzyme digest technique, Single Stranded Conformation Polymorphism analysis and DNA sequencing. We found 10 different G6PD-deficient mutations exist. The two commonest alleles were G6PD Canton 1376 G>T (42.3%) and Kaiping 1388 G>A (39.4%) followed by G6PD Gaohe 592 G>A (7.0%), Chinese-5 1024 C>T, Nankang 517 T>C (1.5%), Mahidol 487 G>A (1.6%), Chatham 1003 G>T (0.8%), Union 1360 C>T (0.8%), Viangchan 871 G>A (0.8%) and Quing Yang 392 G>T (0.8%). Sixty eight percent (88/125) neonates in this study had neonatal jaundice and 29.7% developed hyperbilirubinemia >250 micromol/l. The incidence of hyperbilirubinemia >250 micromol/l was higher in G6PD Kaiping (43.8%) than G6PD Canton (22%) (p< 0.05). There was no significant difference in the incidence of neonatal jaundice, mean serum bilirubin, mean age for peak serum bilirubin, percentage of babies requiring phototherapy and mean duration of phototherapy between the two major variants. None of the 88 neonates required exchange transfusion. In conclusion we have completely characterized the molecular defects of a group of Chinese G6PD deficiency in Malaysia. The mutation distribution reflects the original genetic pool and limited ethnic admixture with indigenous Malays.

Sixty patients with chronic myeloid leukemia (CML) underwent bone marrow trephine biopsy at presentation. All the biopsies were decalcified, paraffin-embedded and stained with H&E, Gomori's reticulin and Masson Trichrome. A detailed study of the histology including the morphology and topographic distribution of megakaryocytes was done. 55 patients presented in chronic phase. Of these there were 37 cases (67%) of CML-granulocytic (CML-G) type and 18 cases (33%) of CML-granulocytic megakaryocytic (CML -GM) type. Five cases presented in blast crisis. 73% of CML-G had low-grade fibrosis while 83% of CML-GM had high-grade fibrosis. This was statistically significant. On follow-up 25% of CML-G went into blast crisis while all the CML-GM patients remained stable to date. Bone marrow biopsy is a useful investigation in patients of CML at diagnosis as it provides prognostic information. Evaluation of megakaryopoiesis, grading of fibrosis and localization of blasts are possible on a trephine biopsy.

The crude methanol extracts of Gelsemium elegans leaves were assessed for their cytotoxic activity using the microculture 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay for cellular viability. This study utilized two different types of human cancer cell lines, CaOV-3 (human ovarian cancer cells) and MDA-MB-231 (human estrogen receptor negative breast cancer cells), allowing for comparison of toxicity of G. elegans against these two cancer cells lines. Our results showed that the methanol extract of G. elegans exhibited high cytotoxicity against the human ovarian cancer cell line CaOV-3 with an IC50 value of 5microg/ml after 96 h incubation. However, G. elegans displayed discernibly less toxicity against the MDA-MB-231 cells with an IC50 value 40microg/ml after 96 h incubation and this effect was dose- and time-dependent, up to 72h and 20-30 microg/ml. In conclusion, our results demonstrated that G. elegans is potently cytotoxic against the human ovarian cancer cell line CaOV-3 and to a lesser extend towards the human breast carcinoma cancer MDA-MB-231 cells, suggesting that the extract is selective towards CaOV-3 cells and may have a chemotherapeutic role for ovarian cancer treatment in the future.
