Types of Bronchitis. Acute infectious bronchitis commonly accompanies or follows a URI; it develops over a couple of days, produces symptoms for 3 to 7 days, and resolves to a cough before normal respiratory function is recovered. Acute irritative bronchitis is triggered by allergies and chemical and other types of environmental irritants.
Reserve propylthiouracil use for those unable to tolerate other treatments (eg, methimazole, radioactive iodine, surgery) Propylthiouracil may be the treatment of choice during and just before the first trimester of pregnancy (strong association of methimazole with congenital malformation during first trimester)
2-Mercaptobenzothiazole, which is mainly used in the rubber industry as a vulcanization accelerator, is very toxic and is considered to be recalcitrant. We show here for the first time that it can be biotransformed and partially mineralized by a pure-culture bacterial strain of Rhodococcus rhodochrous. Three metabolites, among four detected, were identified. 2-Mercaptobenzothiazole (MBT) is the most important and most widely used member of the benzothiazole (BT) family. MBT is typically a rubber additive, but it has also other applications, such as inhibiting biocorrosion in cooling systems or in paper manufacturing.
