In-vitro studies with ceftazidime
Journal of Antimicrobial Chemotherapy, 1981MIC determinations for 275 multiply-resistant nosocomial isolates of enterobacteria showed that ceftazidime was more effective than cefotaxime, cefoxitin or cephalothin. Enterobacter species were the most resistant with 12% isolates resistant to more than 8 mg/l of ceftazidime, but this was still the most active agent.

In vitro studies with hexamethylmelamine
Biochemical Pharmacology, 1977Abstract Hexamethylmelamine (HMM) is effective against a number of human cancers. Studies using mouse lymphoma cells in vitro have shown that HMM is quite non-toxic but is converted by liver microsomes to cytotoxic products. A correlation was found between the ability of analogues of HMM to be demethylated and their antitumour activity.

In vitro Studies with Terconazole
Gynäkologische Rundschau, 2009Terconazole, a new triazole ketal, is a broad-spectrum antifungal agent clinically effective against vaginal candidosis. Terconazole produces a larger zone of inhibition than clotrimazole and isoconazole when tested against Candida albicans in an agar inhibition disk diffusion study at 5 μg/disk and pH 7.3.

Meropenem, a new carbapenem, was compared with imipenem and seven other broad-spectrum antimicrobial agents against approximately 1000 clinical isolates. Meropenem was two- to four-fold more active than imipenem against Gram-negative organisms and its spectrum of antimicrobial activity was wider than those of all other drugs tested.

Journal of Infectious Diseases, 1969
One factor probably responsible in part for the efficacy of gentamicin is the relatively small impairment of its activity by the large numbers of bacteria known to be present in urinary and other gram-negative infections. Table 1 demonstrates the much greater amounts of colistin [1] and carbenicillin [2], as compared with gentamicin, required to ...

In Vitro Studies on a Breathalyzer
Journal of Forensic Sciences, 1972Abstract The Breathalyzer is an instrument designed and developed by Borkenstein for use by law enforcement agencies for rapid, accurate, convenient, and positive recognition of alcoholic intoxication as defined by law. Because the use of the Breathalyzer as a means for determining the alcohol (ethanol) concentration of the blood has ...

Acoustic streaming: An in vitro study
Ultrasound in Medicine & Biology, 2003The aims of this study were, first, to determine if cyst size and cyst-to-transducer distance have an impact upon acoustic streaming and, second, to investigate the effect of cyst content viscosity on acoustic streaming using an artificial ovarian cyst model. Artificial ovarian cysts were constructed and suspended in a tissue-mimicking bath.

Research has conclusively established that normal diploid cells in culture have a limited replicative life span, and that cells from adult organisms have a shorter life span than cells from young organisms or embryos. Although it is unlikely that death of the organism is caused by failure in cellular proliferative capacity, the changes that accompany ...

Immunomodulation with thymopentin:in vitro studies
Medical Oncology and Tumor Pharmacotherapy, 1989Immunomodulation is interpreted as a temporary alert in a certain part of the immune system. The activation of immune competent cells is presented as a possible basic mechanism of this phenomenon. In the absence of a primary stimulus, immunomodulation remains physiologically silent, but it results in a modified immune response if the corresponding ...
