Fenvalerate, a commercially available pyrethroid insecticide, was tested for embryo toxic effects in chick. Different aqueous concentrations of fenvalerate, (0.1 and 0.05 ?g/ml) were injected in albumin of eggs on seventh day of incubation. Recoveries were made at 14th and 20th day of incubation. At 14 and 20 days, morphological studies revealed concentration dependent adverse effects of the insecticide. The developmental effects were loss in weight, reduction in crown rump length and short beak while eyes development showed no observable effects. The present study indicates that fenvalerate, is potentially dangerous to avian development even at very low dose concentrations. It is quite apparent that this insecticide must be used with utmost care and according to well think out plan. Fertilizers e.g. fenvalerate are the important factor for improving soil fertility and crop production. Insects/pests cause serious damage to crops. A common practice to use insecticide/pesticides for the inhibition of these insect/pest populations while maintain the agro-ecosystem. These chemicals are quite dangerous to human health and also cause destruction of non-target species most importantly poultry species present in the ecosystem. The toxic effects of these insecticide e.g. fenvalerate sometimes cause the lethality and mostly cause the developmental disorder thereby presenting economic loss to the farmers. The well-defined concentration of fenvalerate insecticide and their use for the soil productivity is of great importance as it can affect the other species present in that ecosystem and in rural areas the domestic chicken. The economic loss is also associated with it since the abnormal growth of chicken can lead to lethality causing the loss to the chicken breeders and farmers. The highly toxic effects of fenvalerate on the non-targets organisms provides base for the more investigation on the effects of fenvalerate on other different non-target organisms such as fish and avian species. The statistical hypothesis of the present study was found significantly associated with respect to the parameters of morphological abnormalities in chicken (loss in weight, reduction in crown rump length and short beak).

حافظ محمد عرفان

حافظ محمد عرفان
افسوس ہے کہ ۱۴؍ رمضان المبارک کو علامہ شبلیؒ کے حقیقی نواسے حافظ محمد عرفان صاحب وفات پاگئے، ان کا وطن بندول تھا مگر قیام اعظم گڑھ میں تھا، وہ دارالمصنفین برابر آتے اور جمعہ کی نماز بھی یہیں پڑھتے، انہیں قرآن مجید بہت اچھا یاد تھا اور ہر سال تراویح میں اسے سناتے، اس سال بھی ضعف و علالت کے باوجود روزے چھوڑنے کے لیے کسی طرح آمادہ نہ تھے، رمضان کے مقدس مہینہ میں وفات ان کے حسن خاتمہ کا ثبوت ہے۔ اﷲ تعالیٰ پس ماندگان کو صبر و قرار عطا کرے۔ آمین! (ضیاء الدین اصلاحی، مارچ ۱۹۹۴ء)

 

Determinant Factors Affecting Intention of Child Marriage to Adolescents in Banggai Laut

This study aims to look at the determinant factors that affect the intense / intention to do child marriage to adolescents in Banggai Laut. This research method using a cross sectional study. The research sample consisted of 192 teenage students in SMA Negeri 1 Banggai and SMA Negeri 2 Banggai. Chi-square test and multiple logistic regression were used to analyze the data. The results of the bivariate analysis showed that there was an effect of attitude, family drive and behavior control on the intention to do child marriage (p <0.05). The results of the multivariate analysis showed that there was only one variable that had a p value <0.05, namely the family drive variable with p = 0.029. From exp (B) = 4,871> 1 is a risk factor and the Cl value is 95% more than 1 (1,178-20,142) so that OR is significant. This means that respondents who are influenced by family encouragement have a risk of 4,871 times having the intention of engaging in child marriage. It can be concluded that there are many factors that can influence adolescents in engaging in child marriage. All levels of society should protect children together and stop the practice of child marriage in society. The smallest and closest family unit for the child should be able to protect it, not be the main factor that encourages underage marriage.

The Effect of a Preanaesthesia Clinic Consultation on Adult Patient Anxiety in Aga Khan University Hospital; a Cohort Study

Background: Preoperative anxiety is a common perioperative complication, according to studies done it is seen in approximately 11-80% of adults undergoing surgery. Various pharmacological and non pharmacological techniques have been used to reduce preop anxiety. One of the goals of the preanaesthesia clinic is to allay anxiety. Literature shows that a preanaesthesia clinic evaluation reduces anxiety however b current studies done on anxiety and the preanaesthesia clinic have not quantified this reduction. Objective: To determine the reduction in anxiety in patients evaluated in the clinic versus those evaluated in the ward. Study Design: A cohort and before – after study Setting: The surgical outpatient clinics, the gynaecological outpatient clinic, the antenatal clinic, the wards and operating theatres at the Aga Khan University Hospital, Nairobi. Population: All the adult patients scheduled for non-cardiac elective surgical procedures during the study period. Sample size: 44 adult patients with 22 patients in each of the 2 groups i.e. anaesthesia clinic (AC) group and the ward group (W). Methods: 51 adult patients with 28 patients in anaesthesia clinic group and another 23 in the ward were sequentially recruited from both the surgical outpatient clinic, gynaecology outpatient clinic and antenatal clinic. The patient’s State Trait Anxiety Index (STAI) was taken once the patient was booked for theatre. The patient then had a preanaesthesia evaluation either in the preanaesthesia outpatient clinic (PAC) or in the wards. Another STAI score was taken in the preoperative area in theatre on the day of surgery. The patients were then traced back as to whether they had their intervention in the ward or the clinic and hence divided into two groups. The difference in the change of STAI scores in both groups was then analysed. Results: 51 adult patients were recruited i.e. 28 in the clinic group and 23 in the ward group. The majority of the recruited patients were female (n=38). Statistically significant difference was seen in the reduction of the anxiety scores between the clinic group 2.143(C.I=1.384-2.902) and ward group 0.739(C.I=0.168-1.311) with a p value=0.0051.There was also significant difference in reduction in anxiety scores within ward group in the patients with no prior anaesthetic experience having a greater reduction than those a prior anaesthetic experience. There were no other significant differences between the 2 groups. Conclusion: Patients evaluated in the anaesthesia clinic had a greater reduction in their anxiety but it was not as much as hypothesised which may
