Deltamethrin induced toxicity and ameliorative effect of alpha-tocopherol in broilers.

Deltamethrin (DM) is a broad-spectrum insecticide mainly used to protect crops, fruit and vegetables from pests such as mites, ants, weevils and beetles. Birds, animals and human beings living in same ecosystem are directly or indirectly at the risk of exposure to this insecticide leading to substantial decrease in growth. Thus we studied DM induced toxicity and ameliorative effects of alpha-tocopherol in broiler birds. DM was estimated in liver, breast and leg muscles of chickens feeding with only DM or DM with alpha-tocopherol daily for 42 days. Birds exposed to DM showed a dose dependent decrease in body weight on 5th, 6th and 7th weeks as compared to controls, and alpha-tocopherol partially restored the reduction in body weight. DM residue was found higher in liver as compared to breast and leg muscles.

Temporomandibular ankylosis.

Temporomandibular ankylosis is commonly seen in children and young adults. Trauma in childhood is the commonest cause. Treatment of choice is by surgical intervention. Depending upon the local findings a gap arthroplasty or interposition arthroplasty is the procedure carried out. Early mobilisation is recommended.

Betel chewing and dental decay.

A survey was carried out on Four hundred and sixty patients to find out the effects of betel chewing on dental caries & oral hygiene. It was found that among the betel chewers as well as the non betels chewers., the highest caries susceptibility was in the age group of 20-34 years. Also caries susceptibility was higher among the females as compared to males. It was also observed that though the habit of betel chewing reduces the incidence of dental decay, maintenance of oral hygiene is very poor.

Comparative evaluation of marginal leakage of different types of silver amalgam alloys in vitro--a microfluoroscopic study.

A study was carried out in vitro to evaluate the amount of microleakage using seven different Silver amalgam alloy using Fluorescein dye. Among the high copper alloy used in this study, the admixed alloy showed least marginal leakage followed by the high copper lathecut alloy and the high copper spherical alloy. It was also observed that the marginal penetration of the conventional alloy are much more than the high copper alloy.

Factors associated with utilisation of urban MCH/FP programmes--a record study of one centre.

PIP: The utilization and acceptance of different programs provided by an urban maternal and child health/family planning center in India was studied in relation to variables such as distance of residence from the center, age, parity and socioeconomic class. Conducted in March/April 1974 the only method used was that of record study. Use was made of household survey registers and program registers and case cards. The selected center served a population of 41,707. The following were among the study findings: 1) utilization of antenatal, child health and family planning programs was essentially the same by couples residing within a distance of 3.5 kilometers from the center, and any variations observed within this distance was because of other factors such as age or socioeconomic status; 2) beyond 3.5 kilometers, the utilization rate fell rapidly and regularly with increasing distance; 3) there was no association between distance from center and availing of domiciliary delivery facilities by registered antenatals; 4) there was no association between distance from the center and postnatal service to cases of domiciliary delivery; 5) all maternal child health/family planning programs were used mst by persons belonging to socioeconomic class 3 (20.37% of population) followed by socioeconomic class 2 (12.34% of population); 6) the least utilization of all programs was by couples having university education; and 7) the antenatal and child health programs were used most by the youngest wives aged less than 19 years.^ieng

Bilateral posterior open-bite. Abbreviated case report.

A case of bilateral posterior open-bite is reported since it is unusual to find the mandibular and maxillary molars on both sides in infraclusion.

Primary tumours and tumour-like conditions of the mandible.

Reports on comprehensive mandibular tumours are very rare. The present article describes a total of 81 primary tumour and tumour-like lesions of the mandible seen at the University Hospital, Banaras Hindu University, during last 16 years. In the mandible the ratio of odontogenic to nonodontogenic tumors is 1.6:1. Ameloblastomas constitute 56% of the odontogenic tumors. Among the benign mesenchymal tumours of the jaw 58% are neoplastic and 42% are nonneoplastic in which cementoostoid tissue is laid down secondary to inflammatory process. Over all 40 cases are benign 28 potentially malignant (ameloblastoma) and 13 are malignant lesions. Among the malignant mandibular tumours, bone tumours are more common than the soft tissue sarcomas. Microscopically mandibular osteosarcomas are better differentiated than similar tumours in the long bones. Local, segmental, or radical surgery seems to be the treatment of choice in the mandibular tumours.
