The effect of exposure to toluene on plasma concentrations of testosterone, prolactin, luteinising (LH) and follicle stimulating (FSH) hormones was investigated in 47 rotogravure printers (time weighted average air toluene below 80 ppm; blood toluene concentration post-shift 0-19-7-99 umol/l) and compared with a reference group. Increasing exposure concentrations of toluene (concentrations <5 t...

OBJECTIVES Previously, the author reported a cluster of 11 cholangiocarcinoma cases exposed to 1,2-dichloropropane (1,2-DCP) and/or dichloromethane (DCM) in an offset proof-printing company. Before that report, the association between the two chemicals and cholangiocarcinoma had not been known. The current study describes two cholangiocarcinoma patients exposed to 1,2-DCP or DCM in different of...

Mortality of newspaper workers from lung cancer and bronchitis 1952-66. The mortality experience of 3 485 men who worked full-time in the newspaper printing industry in London and Manchester and died in the period 1952-66 has been analysed for occupation and cause of death. There was an excess of deaths from cancer of the lung and bronchus (I.C.D. 162, 163) in printing trade workers as a whole ...

A historical cohort study of the printing industry was established after an anecdotal report of a cluster of cases of bladder cancer in a newspaper factory in Manchester. The cohort comprised some 9500 men who were members of one or other of two trade unions (the NGA and NATSOPA) in the Manchester area between 1949 and 1963. During the follow up period (1949-83) 3482 deaths occurred among men b...

1. Background Three former and current employees of a printing plant in Osaka were reported having developed biliary tract cancer, announced the Ministry of Health, Labour and Welfare in May 2012. Those workers at the printing room used to handle chlorinated hydrocarbons as ink cleaner all day, according to their claims for workers’ compensation filed on 30 March 2012.

The textile printing industry in South India employs a great number of workers that may possibly be exposed to toxic compounds. In the present study, subjects from textile printing units were investigated for the presence of genetic damage in their peripheral blood lymphocytes using micronucleus assay. Proliferation was also investigated using a nuclear division index. It was found that the mic...

BACKGROUND In 2013, an unusually high incidence of biliary tract cancer among current or former workers of the offset color proof printing department of a printing company in Osaka, Japan, was reported. The purpose of this study was to examine whether distance from the printing factory was associated with incidence of biliary tract cancer and whether incident biliary tract cancer cases clustere...

Three-dimensional (3D) printing technology has revolutionized tissue engineering field because of its excellent potential of accurately positioning cell-laden constructs. One of the main challenges in the formation of functional engineered tissues is the lack of an efficient and extensive network of microvessels to support cell viability. By printing vascular cells and appropriate biomaterials,...
