Maritime in transit care.

Operation GRITROCK saw the first operational deployment of the Maritime In Transit Care team from the Role 2 (Enhanced) (R2(E)) Medical Treatment Facility, which is able to provide Damage Control Surgery and the limited holding of patients, situated on board RFA ARGUS. Whilst the Medical Emergency Response Team demonstrated the capability of advanced military Pre-Hospital Emergency Care (PHEC) on Op HERRICK, the need to provide a similar high level of care on contingency operations was recognised. Op GRITROCK allowed for the continued exploration of a maritime capability from an established R2(E) platform whilst providing medical evacuation capability for a significant population at risk distributed over a large Joint Operation Area. Although the patient load during the operation was low, key lessons were learnt and opportunities identified to further develop the newly recognised sub-speciality of PHEC, both medically and logistically, and these will be discussed in this article.

Microbial metabolism of quinoline and related compounds. IX. Degradation of 6-hydroxyquinoline and quinoline by Pseudomonas diminuta 31/1 Fa1 and Bacillus circulans 31/2 A1.

Two strains, using 6-hydroxyquinoline as sole source of energy, carbon and nitrogen, have been isolated. These bacteria, designated 31/1 Fa1 and 31/2 A1, are also able to degrade quinoline. According to their physiological properties strain 31/1 Fa1 has been identified as Pseudomonas diminuta and strain 31/2 A1 as Bacillus circulans. 6-Hydroxy-2-oxo-1,2-dihydroquinoline was found as intermediate in the degradation of 6-hydroxyquinoline and quinoline. 2-Oxo-1,2-dihydroquinoline was the first metabolite in the degradation of quinoline.

Microbial metabolism of quinoline and related compounds. V. Degradation of 1H-4-oxoquinoline by Pseudomonas putida 33/1.

A bacterial strain was isolated with the ability to use 1H-4-oxoquinoline as the sole source of carbon, nitrogen and energy. On the basis of its physiological properties, this isolate was classified as Pseudomonas putida. 1H-3-Hydroxy-4-oxoquinoline, N-formylanthranilic acid, anthranilic acid and catechol were identified as intermediates in the degradation pathway. The latter was further degraded by ortho-cleavage. The enzymatic conversion of 1H-4-oxoquinoline into 1H-3-hydroxy-4-oxoquinoline requires oxygen and NADH. Experiments with 18O2 showed that the oxygen consumed in this enzymatic reaction is derived from the atmosphere.

Immunological features of preeclampsia: increased frequency of antilymphocyte antibodies, but not of immune complexes.

Using two methods for detecting circulating immune complexes (CIC)--inhibition of antibody-dependent cell-mediated cytotoxicity and solid-phase C1q assay--we were unable to demonstrate CIC in sera from preeclamptic patients and from healthy pregnant women. Antilymphocyte antibodies were found much more frequently in multiparous women suffering from preeclampsia-like disease than in healthy multiparous pregnant control patients. They were not detected in primigravida uncomplicated or preeclamptic pregnancies. It is suggested, therefore, that preeclampsia may have a different etiology in the multiparous woman than in the primigravida.
