Evaluation of lighting conditions in relation to visual comfort in workplaces of weavers in a textile mill.

The present investigation was undertaken to examine the lighting conditions in a weaving shed and also to assess visual comfort of the weavers and their visual preferences to the lighting levels. A light meter was used for measurement of the illuminances. Comfort vote cards and preference vote cards were administered on almost all the weavers (N = 95). The results indicated that the illumination levels were very low compared to the Indian Standard (1966) or IES standard (1973). A substantial proportion of the weavers had no visual comfort at work and expressed their preferences for higher illumination levels for comfort, safety, and optimum work performance. The results have been discussed and appropriate measures have been suggested for improved lighting in a cost-effective manner.

[Coexistence of cervico-brachial neuralgia and backache among textile industry workers].

The paper has been aimed at searching for the correlation between neck and arm pain and low back pain to test the rate of concomitance of both disorders and the order of their appearance. The studies have been carried out in two big light industry plants in Lódź. The coexistence of the pain syndromes has been found to be frequent, low back pain usually developing first. It seems that the occurrence of one of those disorders disturbs the functioning of the whole vertebral column and thus predisposes to the development of the other one.

[Preparation of lysozyme immobilized on textile carriers and its use in treating suppurative wounds].

Immobilized forms of lysozyme were prepared by its covalent binding on dialdehyde cellulose and polycaproamide fibres as woven and knitted fabrics respectively. The preparations were estimated by the content of protein and bacteriolytic activity. The lysozyme activity per 1 g of the carrier and the protein content on dialdehyde cellulose were several times higher than those on polycaproamide while the specific activity of lysozyme on the polycaproamide carrier was somewhat higher than that on dialdehyde cellulose. The effect of the immobilized lysozyme in treatment of purulent wounds was studied on albino rats. It was shown that the periods of the wound healing with the use of the immobilized lysozyme were shorter than those with the use of native lysozyme. Cytological and morphological investigation of the wound wall confirmed the higher efficacy of the lysozyme immobilized forms in treatment of purulent wounds as compared to the use of the native enzyme.
