We have observed and re-evaluated the histology of the skin of the horse, using samples from four Thoroughbreds. The skin was composed of the usual three components: epidermis, dermis and subcutis. In particular, the dermis was found to have three fibrous components: a papillary layer, a reticular layer and a cordovan-leather tissue layer. The cordovan-leather tissue layer was subdivided into a...

The Hokkaido sika deer (Cervus Nippon yesoensis), the largest and most abundant of the sika deer subspecies in Japan, has recently attracted new attention as a target for leather production, in addition to its meat value. To provide fundamental data for facilitating the effective use of skin for leather, the histological properties of skin at the shoulder, back and abdominal regions of male and...

The observation of many multiple sclerosis (MS) cases among shoe and leather workers prompted a survey of the risk of MS in this working population. Eighty-one patients with definite or probable MS alive in Florence on May 1st 1976 were interviewed regarding their occupation at onset of the disease. Five of the 41 patients working at the time had worked in shoe a leather factories. The relative...

Corona discharge has been used widely to modify polymer and textile materials because it can be operated at an atmospheric pressure in air.This method has been confirmed to be simpler and more practical than any other chemical and physical methods because the samples can be quickly treated under atmosphere pressure and it is environmentally friendly too. In this study, we have studied wettabili...

Leather industry, one of the polluting industries because of generation of huge amount of liquid and solid wastes, also emits obnoxious smell because of degradation of proteinous material of skin and generation of gases such as NH3, H2S and CO2. Solid wastes are raw trimmings, fleshings, chrome shavings, buffing dusts and keratin wastes. Accumulation of these wastes lead to sludge problem and c...

The purposes of this research were to develop and to monitor the antecedent factors which directly affected the success rate of new product development. This was a case study of the leather industry in Bangkok, Thailand. A total of 350 leather factories were used as a sample group. The findings revealed that the new product development model was harmonized with the empirical data at the accepta...

Basic chromium sulphate is the most versatile and common tanning agent in the leather industry. Under certain circumstances, the oxidation of the trivalent chromium salts into the hexavalent compounds, which are used in leather manufacture, is a crucial issue. In this study, different proportions of basic chromium sulphate were used in tanning and re-tanning processes according to a commonly us...

Chitosan is a biopolymer that is being increasingly used in distinct areas such as pharmaceutical, biomedical, cosmetics, food industry and agriculture. Among the interesting biological activities that have been ascribed to chitosan, the antimicrobial activity is probably the one that generates the higher number of applications. Considering that feet present favorable conditions for microorgani...

Tannery workers are at potential exposure to detrimental agents rendering them vulnerable to respiratory and dermal problems. Thus by performing pulmonary functions among leather tannery workers, we can decipher the effect of chromium and leather dust on lung functions and also the decline of respiratory functions with increasing years of exposure to leather dust. Pulmonary functions were asses...

The leather bass Dermatolepis dermatolepis (Boulenger, 1895) is a poorly known grouper living on coral and rocky reefs in the eastern Pacific Ocean. One of only three species in the genus Dermatolepis (family Serranidae, subfamily Epinephelinae), the leather bass distribution ranges from southern California to Ecuador, including the Gulf of California, the Galapagos Islands and other offshore i...
