The action and interaction of benzylpenicillin and gentamicin on Streptococcus faecalis was studied using mainly turbidimetric methods. The minimum antibacterial concentration (MAC) of each antibiotic lay considerably below the conventionally determined minimum inhibitory concentration, and levels of the two agents exceeding the MAC were necessary in order to obtain a synergic interaction. Evid...

A double tracer autoradiographic technique using "'I-iodo-antipyrine and "C-deoxyglucose is presented for the simultaneous measurement of blood flow and cerebral glucose utilization in the same animal. '"I is a gamma emitting isotope with a half life of 8.06 days and can be detected with adequate resolution on standard autoradiographic films. Autoradlograms are made before and after decay of "'...

One of the major signs of severe organophosphate poisoning is seizures. Previous studies have shown that both muscarinic agonist- and organophosphate-induced seizures require activation of muscarinic acetylcholine receptors in the central nervous system. Seizures induced by the muscarinic agonist pilocarpine require the M1 receptor and are modulated by cannabinoid CB1 receptors. In this study, ...

resistance of streptococcus pneumoniae against penicillin is considered to be of great importance. while low-resistant strains could be treated by penicillin, treatment of highly resistant strains is very difficult and needs broad-spectrum antibiotics. this study was performed in imam khomeini medical center, tehran, iran, from 1999 to 2001 to evaluate pneumococcal resistance against penicillin...

Reflex seizures are seizures that are elicited by sensory or cognitive stimuli. These stimuli can be very diverse but are usually highly specific within one patient. The type of seizures that are induced by these stimuli can be tonic-clonic seizures, myoclonic jerks with or without absences, and absences with facial myoclonus. Focal seizures can also occur. A wide range of different stimuli hav...

Mice were administered anticholinesterase pesticides dichlorvos (DDVP) or methomyl (MET). Both DDVP and MET induced dose-dependent seizures and lethality in mice. The muscarinic antagonist atropine (ATR, 1.8 mg/kg) did not prevent seizures but diminished the lethality induced by DDVP or MET. The nicotinic antagonist mecamylamine (MEC, 1 mg/kg) affected neither DDVP-induced seizures nor DDVP- an...

objective(s):a growing interest has recently been attracted towards the identification of plant-based medications including those with protective effects against cognitive impairment. sesamol has shown promising antioxidant and neuroprotective effects, therefore, we aimed to evaluate its therapeutic potential in epilepsy which is commonly associated with oxidative stress and cognitive impairmen...

cognitive impairment in epileptics may be a consequence of the epileptogenic process as well as antiepileptic medication. thus, there is need for drugs, which can suppress epileptogenesis as well as prevent cognitive impairment. in the present study, the effect of khamira marwarid (kah 1 ), a formulation based on indian system of unani medicine, was evaluated on the course of pentylenetetrazole...

Introduction. Syphilis incidence has increased in the US in the last decade. Jarisch-Herxheimer reaction (JHR) is a well-documented adverse effect of penicillin treatment in syphilis. Stroke has not been reported as part of its phenomenology. Case Report. A 57-year-old man presented with worsening memory. His minimental status examination score was 14/30. Serum RPR test was positive and VDRL te...
