Minocycline was added to normal and hyperlipemic serum samples in concentrations of 1 approximately 10 mcg/ml. These specimens had similar protein contents. Chemically extractable minocycline was quantitated fluorometrically. Hyperlipemic serum (cholesterol 480 mg/100 ml; triglycerides 321 mg/100 ml) yielded an average of 50% less minocycline than did normal serum (cholesterol 170 mg/100 ml; tr...

BACKGROUND Minocycline has anti-apoptotic and anti-inflammatory effects in vitro, and extends survival in mouse models of some neurological conditions. Several trials are planned or are in progress to assess whether minocycline slows human neurodegeneration. We aimed to test the efficacy of minocycline as a treatment for amyotrophic lateral sclerosis (ALS). METHODS We did a multicentre, rando...

Eighty-one strains ofStaphylococcus aureus that appeared to be tetracycline resistant on the basis of a preliminary disc-diffusion test were examined fro resistance to tetracycline and to the semi-synthetic tetracycline, minocycline. Minimum inhibitory concentration (m.i.c.) values for both drugs were determined after induction of the strains by growth for 2 h in sub-inhibitory concentrations f...

A patient presenting with a pyrexial illness and transiently deranged liver function tests is described. He had been taking minocycline for 12 months. The causal association with this drug was demonstrated by withholding and then rechallenging with minocycline. This report documents drug fever as an adverse reaction to minocycline, and its late onset is of added interest.

Introduction: Epilepsy is a neurological disorder that affects 1-2% of the world population and about 30% of patients are resistant to antiepileptic drug therapy. Therefore, new treatment alternatives are needed. In the present study, the possible neuroprotective effect of minocycline against epileptiform activity induced by pentylenetetrazole (PTZ) was assessed. Methods: Conventional intra...

Objective(s): Several lines of evidence showed that minocycline possesses antioxidant and anti-inflammatory properties. This study aimed to demonstrate the effects of minocycline in rats subjected to chronic constriction injury (CCI). Materials and Methods: In this study four groups (n = 6–8) of rats were used as follows: Sham, CCI, CCI + minocycline (MIN) 10 mg/Kg (IP) and CCI + MIN 30 mg/Kg (...

INTRODUCTION Primary open-angle glaucoma (POAG) is one of the leading causes of blindness. Activation of optic nerve head astrocytes (ONHA) and loss of trabecular meshwork cells (TMC) are pathognomonic for this neurodegenerative disease. Oxidative stress and elevated levels of transforming growth factor beta (TGFbeta) play an important role in the pathogenesis of POAG. This study investigates t...

Practice Pointers Acne vulgaris, the most common skin condition in adolescence,1 is not only bothersome, but also can lead to negative self-image and social withdrawal. For years, minocycline was a first-line treatment because of its convenience (e.g., absorption not affected by food, could be taken once a day because of its longer half-life), rapid onset of action, and the assumption that its ...

In neuropathic pain the repeated minocycline treatment inhibited the mRNA and protein expression of the microglial markers and metalloproteinase-9 (MMP-9). The minocycline diminished the pronociceptive (IL-6, IL-18), but not antinociceptive (IL-1alpha, IL-4, IL-10) cytokines at the spinal cord level. In vitro primary cell culture studies have shown that MMP-9, TIMP-1, IL-1beta, IL-1alpha, IL-6,...

An outbreak of meningococcal disease occurred among basic combat trainees at Fort Lewis, Wash., in the first 3 months of 1971. After five recruits developed meningitis within a 2-week period, 8,721 recruits were given 100 mg of minocycline every 12 hr for 5 days. No new cases of meningococcal disease occurred for almost 5 weeks. Then six additional cases occurred among recruits who had entered ...
