Eurycoma longifolia (E. longifolia) which is better known locally as Tongkat Ali is an indigenous plant in Malaysia. It belongs to the family of Simaroubaceae and is popular as a traditional medicine for its aphrodisiac properties. Throughout the years, several studies have been conducted to prove its effect on aphrodisiac action, antimalarial, antibacterial and anxiolytic properties but its effect to the cardiovascular system had not been fully explored. This study was aimed to demonstrate the changes that take place in the isolated heart following the injection of the extract. Methods: Three parameters that were measured included the coronary perfusion pressure (CPP), the left ventricular developed pressure (LVDP) and the heart rate (HR). Eighteen isolated rat hearts were used and were divided equally into three groups. The first group was to observe the effect of Isoprenaline, a β agonist while the second group was to see the effect of sodium nitroprusside (SNP), a nitric oxide (NO) donor. The dose which gave the maximum effect for these two positive controls was used to compare with the effect of E. longifolia water extract in the third group of rats. Isolated heart was mounted using the Langendorff apparatus and perfused with modified Krebs-Henseleit buffer. Doses of controls and the extract were instilled through an injection port, and the effect of each dose was monitored. Results: E. longifolia extract was found to reduce the CPP in normotensive rat at two of the highest doses. A dose of 1.0 mg of the extract reduced the CPP significantly from 34.52 ± 4.99 mmHg of the baseline value to 31.99 ± 4.93 mmHg while the dose of 10.0 mg of the extract reduced the CPP significantly to 32.67 ± 3.89 mmHg. However, there were no significant changes of effect of the extract on the LVDP and HR as compared to control. Conclusion: These early findings suggest that E. longifolia extract may have vasodilatory property, which supports its traditional usage with minimum cardiovascular side effects.

Introduction: To review the gestational age at diagnosis, method of diagnosis, pregnancy outcome and maternal complications of prenatally diagnosed lethal foetal anomalies. Methods: Retrospective review of 25 women who had aborted or delivered foetuses with lethal anomalies in a tertiary hospital in 2011 based on patient medical records. Results: There were a total of 10,088 deliveries, in which 25 (0.24%) women were found to have conceived foetuses with lethal anomalies. All of them were diagnosed by prenatal ultrasound and only 7 (28.0%) had both prenatal ultrasound and genetic study done. The women’s mean age was 29.9 years old. The mean gestational age at diagnosis of lethal foetal anomalies was 25.5 weeks (SD=12.5) and mean gestational age at termination of pregnancy (TOP) or delivery was 28.5 weeks (SD=12.5). Seven (28%) women had early counseling and TOP at the gestation of < 22 weeks. Beyond 22 weeks of gestation, eight (32%) women had TOP and ten (40%) women had spontaneous delivery. Twenty (80%) women delivered or aborted vaginally, three (12%) women with assisted breech delivery and two (8%) women with abdominal delivery which were performed due to transverse foetal lie in labour and a failed induction, leading to emergency hysterotomy complicated by hysterectomy due to intraoperative finding of ruptured uterus. Overall, the associated post-partum adverse events included post-partum haemorrhage (12%), retained placenta (12%), blood transfusion (8%), uterine rupture (4%) and endometritis (4%). Mean duration of hospital stay was 6.6 days (SD 3.7 days). Conclusion: Late diagnosis of lethal foetal anomalies leads to various maternal morbidities, in this case series , which could have been prevented if they were diagnosed and terminated at early trimester. A new direction is needed in our local practice.

The purpose of this study was to determine the timing and sequence of emergence of the first 28 permanent teeth in a cross-section of Malay children in the district of Kota Bharu, in northeastern Peninsula Malaysia. The sample consists of 478 boys and 908 girls of Malay descent aged between 5-19 years. The criterion for tooth emergence was the appearance of the tooth through the gingivae. Descriptive statistics were calculated and probit regression analysis performed to determine the mean age of emergence of the permanent dentition. The mean age at emergence was found to conform to general trends, with emergence seen earlier in girls than in boys. Comparisons were made with the Chinese (Hong Kong) and the Punjabi (Chandigarh) profiles, which showed earlier emergence timings in those ethnic groups. The emergence timing in Malays, however, was earlier than in Thais (Central Thailand). The sequence of emergence was determined by referring to the mean age of tooth emergence of individual teeth and conforms to the general trend seen in other studies.

Melia azedarach L. (Meliaceae) is a botanical species with focal point of global research for its biological properties. The Melia azedarach tree is distinguished by its rapid growth, its adaptation to different temperate zones, as well as its insecticidal properties. All this made us think of exploiting it in biological control against different stages of mosquitoes. To this end, we aim, through the present work, to evaluate the effectiveness of Melia azedarach extracts against Culex pipiens mosquito. More specifically, our study focuses on determining the chemical composition of Melia almond oil, as well as the larvicidal, ovicidal and repellent activities on Culex pipiens L. mosquito as well as the activities of acetylcholinesterase (AChE) and glutathione-S-transferase (GST). Almond oil was extracted by a Soxhlet and subjected to gas chromatography–mass spectrometry (GC/MS). The yield was found to be 35.17%. The chemical composition revealed the presence of various phytoconstituents. A total of 7 compounds were identified, the main ones being 9,11-Octadecadienoic acid, methyl ester, (E,E)- (79.32%), 9-octadecenoic acid (Z)-, methyl ester (13.24%), hexadecanoic acid and methyl ester (3.69%). The larvicidal bioassays were performed according to the protocol recommended by the World Health Organization with concentrations varying from 20 to 80 mg/L depending on the exposure time (24, 48 and 72 hours). The almond oil exhibited remarkable larvicidal activity against fourth instar larvae and the lethal concentrations were determined (LC25= 23.70 mg/L, LC50=35.49 mg/L, LC90=79.61 mg/L). The results also showed that the oil caused an ovicidal activity with a significant effect on egg hatch. The recorded hatching percentages were respectively 88.79% and 72.40% for the LC25 and LC50, and this compared to the control series. Moreover, this oil exhibited significant repellency against adult mosquitoes. Furthermore, the enzymatic measurements performed on LC50 and LC90 treated larvae revealed a neurotoxic activity and a stimulation of the detoxification system as evidenced, respectively, by an inhibition of AChE and induction in GST activity. Overall, our data proved that Melia azedarach almond oil could be considered as a potent biorational alternative to synthetic insecticides for mosquito control.
