Severely malnourished children (26), weight for age 55.27±3.17, were identified in a colony of predominantly Muslim urban
slum dwellers of low economic status. An equal number of normally nourished children matched for age, sex and per capita income
were identified. A strong relation was found between nutritional status of the subjects and educational level of their mothers
(P<0.025). Father's education was unrelated to childrens' nutritional status. A thirty seven point questionnaire was administered
to the mothers to record their nutritional knowledge, attitudes and practices (KAP). Analysis revealed that better KAP in
relation to 16 of these 37 questions was not associated with better nutritional status. Seven questions were found to have
only a weak association. The remaining 14 questions were identified as important for a nutrition education programme. Comparison
of nutritional KAP score based on these 14 questions in case of mothers of normal and severely malnourished children revealed
a significantly higher score in the former. Questions related to growth monitoring and breast feeding were not found to be
important. No significant association was found between mothers' KAP and educational level. It is concluded that (i) Maternal education and KAP are significantly and independently associated with childrens' nutritional status. (ii) The content areas of knowledge, attitudes and practices significantly associated with nutritional status pertain to nutritional
requirements of children, nutritional value of foods, immunisation, hygiene, oral rehydration and diarrhea. 相似文献

Dietary aflatoxin and hepatitis B virus infection may play arole in generating the p53 tumor suppressor gene codon 249 hotspotmutation found in human hepatocellular carcinomas (HCCs) fromQidong (China) and southern Africa. No data are available onthe HCC site-specific mutation of the p53 gene in hepadnavirus-infectedanimals exposed to AFB1. We have searched for the presence ofp53 gene codon 249 mutations in both duck hepatitis B virus(DHBV) positive and negative HCCs of domestic ducks from Qidong,where the human p53 hotspot is so prevalent, as well as in duckHCCs experimentally induced by AFB1. Direct sequencing of DNAamplification products encompassing p53 codon 249 did not revealany mutations in 11 HCCs from Qidongducks, regardless of thestatus of DHBV infection. In addition no mutation was detectedin four HCCs from AFB1-treated ducks. This contrasts with thehuman data; however, in humans, the mutation and the preferentialbinding of AFB1 to codon 249 occurs at the third nucleotideG, while in duck, the codon 249 lacks this G residue. The DNAsequence of adjacent codons is also different in the two specieseven though the amino acid sequence is identical. This may explainthe low frequency of mutation we have observed. In addition,species differences in metabolism and DNA repair could influencethe occurrence of codon 249 mutations. 相似文献

V. K. Puri M.R.C.P. D.M. V. Pathak M.D. A. Mehrotra M.D. P. N. Saxena M.D. 《Indian journal of pediatrics》1984,51(4):407-411
Systolic time intervals (STI) were measured from simultaneous high speed recordings of electrocardiogram, phonocardiogram,
and carotid artery trace in 47 children of anemia with or without congestive heart failure (CHF), and in 20 healthy normal
children. Group I comprised 20 healthy controls with a mean Hb level of 13.65±0.73 gm percent, group II of 37 anemic children
with a mean Hb level of 7.3±1.01 gm percent, without any evidence of CHF: Group III of 10 severely anaemic children with a
mean Hb level of 2.75±0.82 gm percent with overt CHF. Electromechanical systole (QS2) pre-ejection period (PEP), left ventricular
ejection time (LVET) and the ratio of PEP/LVET were studied and compared in various groups. PEP/LVET ratio was found to be
0.265±0.04, 0.363±0.07 and 0.407±0.06 in groups I, II, III cases respectively. The mean PEP/LVET ratio was significantly prolonged
in groups II and III when compared with group I (p<.001). Further mean PEP/LVET ratio was significantly greater in group III
subjects when compared with group II patients (p<.001). Thus it seems that LV dysfunction sets in early in cases of anemic
children and as the severity of anemia increases. left ventricular dysfunction proportionately increases, ultimately resulting
in congestive heart failure. 相似文献

Objective To evaluate the possible role of environmental exposure to lead as a risk factor for prostate pathology in patients suffering from prostate cancer (PCA) and benign prostate hyperplasia (BPH). Methods Blood lead (BPb) level was determined in PCA and BPH cases using a graphite furnace Atomic Absorption Spectrophotometer and compared with those in a control group living in the similar socioeconomic environment. Results BPb was significantly higher in PCA and BPH cases than in normals (P<0.05). Blood levels of zinc and copper were significantly lower in PCA and BPH cases when compared with controls (P<0.05). In all the three groups, a statistically significant positive correlation between lead and thiobarbituric acid reactive substances (TBARS) measured as malondialdehyde, and negative correlation between blood lead and antioxidant GSH level, indicative of possible generation of reactive oxygen species, were also observed after adjusting for age as a possible confounders. However, positive association between blood lead and TBARS was relatively higher in PCA patients (r=0.77, P<0.05) than in BPH (r=0.32, P<0.05) and normal (r=0.30, P<0.05).Conclusion These results with limited power seem to suggest for the first time that environmental exposure of aging males to lead may be a risk factor for prostate cancer and/or benign prostate hyperplasia possibly through generation of reactive oxygen species and/or reducing the level of zinc which acts as a cellular growth protector. 相似文献

Public social services, such as basic health care, represent the effective option for the poor, especially in the rural areas of low-income countries. The quality of such services are at present extremely deficient, largely due to resource constraints and lack of political will to make them function effectively. The state can no longer provide the comprehensive services it has in the past and which were highly successful in a number of 'high-achieving' developing countries. Yet, the state must turn priority attention to providing public services for the poor, in order to close the widening gap between rich and poor. It needs to do this in partnership with the population it aims to reach, through effective linkage with grass-roots organizations and with the support of non-governmental organizations. Giving 'voice' and participation to the population can not only increase the resource base for public services, but can also significantly improve the accountability of providers and lead to a cost-effective option for the poor. 相似文献
