In female rats, there were increases in the incidence of CPN in all exposure concentrations and in the severity at 1800 ppm, indicating that CPN was increased by mechanisms in addition to those related to α2μ-globulin.

HARMFUL IF INHALED. 0000010245 00000 n In order to evaluate the potential of MIBK to induce toxic and carcinogenic effects following chronic exposure, groups of 50 male and 50 female F344/N rats and B6C3F1 mice were exposed to MIBK at concentrations of 0, 450, 900, or 1800 ppm by inhalation, 6 h/day, 5 days per week for 2 years. - [4-Methyl-2-pentanone ; Methylisobutyl ketone, MIBK]:100ppm 410mg/m3 B. 0000004218 00000 n

The primary targets of MIBK toxicity and carcinogenicity were the kidney in rats and the liver in mice. There were also increases in renal tubule hyperplasia at all exposure concentrations, and in adenoma and adenoma or carcinoma (combined) at 1800 ppm; these lesions are thought to represent a continuum in the progression of proliferative lesions in renal tubule epithelium. �k��j�ŞK�������ϼ8 )ӣOΊ*4�.s�,CU�T¬_%r�8O"4Ψ��V�8���y���!�f����|�/=c�l �5�p ����*q�����f�Cp�T���薚��v�:�p�46��B&f���x��X$)�VҬ�М ��0�'�Lc�W� �S�I��֭� ~�T����=���{���9 h�b```"SVi&~�g`��0p4�9�8��!Y�`�D�%��}�������Lj �0�@E|���@Z��������-�8!��P�������uBp�����l�鎧u�_��g����� w�c^D�Q 0000004813 00000 n 0
