[Effect and effectiveness of iodine brine baths in a spa].

On the occasion of closing the research department of the Paracelsus Institute in the iodine salt spa, Bad Hall, the results of more than 30 years' research work in this institute are summarized. This work concerned the therapeutic effects of iodine on circulatory illnesses, especially hypertension, bronchitis and degenerative eye diseases. Controlled studies in patients showed significant cure effects of the iodine springs. Other studies demonstrated an influence of iodine on peripheral blood vessels, blood viscosity, connective tissue and vision and demonstrated the scavenger function of iodine, too. The different therapeutic forms of iodine administration (baths, sprays, iontophoresis, drinking cures) are described and the potential side effects of a cure in an iodine spa, notably temporary hypothyroidism, are mentioned.

The nature of the copper ions in the membranes containing the particulate methane monooxygenase from Methylococcus capsulatus (Bath).

It is shown that the particulate methane monooxygenase (pMMO) has an obligate requirement for copper. The MMO activity in the particulate fractions obtained from Methylococcus capsulatus (Bath) cells is found to increase with increasing copper content of the membranes. The enzyme activity from membranes obtained from cells grown at low copper levels can be stimulated further by the addition of Cu(II) ions to the assay medium. The membrane-bound copper ions can exist in both Cu(II) and Cu(I) forms. EPR and magnetic susceptibility characterizations of the membranes indicate the presence of an exchange-coupled trinuclear Cu(II) cluster when the bulk of the copper ions is oxidized. However, the functional form of the enzyme is the reduced or partially reduced form. The copper ions in the membrane fractions as isolated often exhibit a high level of reduction. An EPR spectrum with one unpaired electron spin delocalized over three copper nuclei has been observed for the two-electron reduced trinuclear copper cluster. The high correlation between the copper level in the membranes and enzymatic activity as well as the high reactivity of the reduced copper clusters toward dioxygen strongly indicate that the membrane-bound copper ions constitute the active sites of the pMMO.

[Quantitative assessment of cerebral blood flow by 123I-IMP SPECT: venous sampling method with hand warming in the water bath].

In order to establish a noninvasive, quantitative method for measuring regional cerebral blood flow (rCBF) by N-isopropyl-p-[123I]iodoamphetamine (123I-IMP) SPECT, we attempted to employ continuous venous sampling instead of arterial sampling. Forty two patients with cerebrovascular diseases were classified into two groups, with (group II: n = 35) and without (group I: n = 7) hand warming. In group II, either hand was warmed, wrapping in a hot blanket (group IIA) or immersed in a 44 degrees C water bath (group IIB). In each patient, immediately after intravenous bolus injection of 222 MBq IMP, arterial and venous blood samples were collected continuously for 5 min from the radial artery and the cubital vein, respectively. By octanol extraction, IMP was divided into the unmetabolized and metabolized fraction. The ratio of 123I-IMP radioactivity of venous blood compared to arterial blood (pass ratio, referred as %PR) was calculated in three fractions, whole blood, unmetabolized, and metabolized fraction. By using these parameters, we assessed the possibility to estimate the amount of unmetabolized IMP fraction of arterial blood, usually used as an input function, from venous samples. In group I, %PR demonstrated a considerable variation between individuals (whole IMP, 47.5 +/- 24.6% (mean +/- SD): unmetabolized IMP, 46.0 +/- 24.5%: metabolized IMP, 51.8 +/- 27.4%). In group II, especially in group IIB, both increase of %PR value and the decrease in variation (whole, 77.9 +/- 5.6%: unmetabolized, 75.7 +/- 5.7%: metabolized, 86.7 +/- 8.7%) were observed, which permitted the further calculation based on the assumption that %PR value was constant in each IMP fraction (whole blood and unmetabolized fraction).(ABSTRACT TRUNCATED AT 250 WORDS)

Treatment of parapsoriasis en plaques, mycosis fungoides, and Sézary's syndrome with trioxsalen baths followed by ultraviolet light.

Three patients with parapsoriasis en plaques (PEP), fifteen with mycosis fungoides (MF), and one with Sézary's syndrome (SS) were given a bath to which a small amount of trioxsalen solution had been added, and then exposed to ultraviolet (UV) radiation from a bank of dysprosium lamps. Within 2--6 months of this treatment the skin lesions healed completely or almost completely in all 3 patients with PEP, in all 7 with MF stage II and in 4 of 5 with MF stage III. Two patients with MF stages IV--V showed a fair degree of improvement. One with erythrodermic form of MF responded, but poorly. The patient with SS and the one with erythrodermic MF responded with severe phototoxic reactions.

[Conductivity of the dialysis bath. Measurement, significance and electrolyte and clinical correlations].

The problem of the conductivity of dialysing solution is discussed. Measurement technique is analysed, highlighting the possibility of error connected with variations in the temperature of the dialysis bath, its mixture, the presence of air bubbles and the presence of dissolved substances that are not electrical charge carriers, and stressing the absolute proportionality with free ions and not with total ions. On the basis of these observations, the lack of any real, reliable correlation between conductivity and electrolytic composition of the dialysing solution unless particular conditions are respected is pointed out. Most important of these are exact knowledge of the composition of the mother solution and the degree of purity of the water. In conclusion, the imprecision of the values given by clinical and technological tradition and widely accepted is pointed out. Such values do not correspond to correct measurement.

A case of giant bathing trunk naevus with neurofibroma-like change.

It is recognized that cells of melanocytic naevi may resemble neuroid structures and the term neurotization has been used to describe this phenomenon. This may result in difficulty in the histological differentiation between naevi and neurofibromas. We report the case of a patient with a giant bathing trunk naevus which has undergone marked neurotization and in whom there had been diagnostic difficulty.

BATHE: an approach to the interview process in the primary care setting.

The American health care delivery system is undergoing a rapid and substantive change. Health care providers are now expected to depart from their traditional role of healers of the sick to a more comprehensive one of including maintenance of health as well. Incentives are being put in place to encourage physicians to interdict disease at its early, more curable stage and to detect and treat previously unrecognized or underrecognized conditions. Research indicates that there is a great need in the area of mental heath. In order for primary care practitioners to recognize patients who have mental health problems with some facility, it is recommended that they employ the BATHE technique for developing a psychosocial history. This technique will enable primary care practitioners to succinctly and efficiently uncover psychosocial problems while at the same time to lend support to patients as they attempt to come to grips with these issues.

Residue study of mebendazole and its metabolites hydroxy-mebendazole and amino-mebendazole in eel (Anguilla anguilla) after bath treatment.

Mebendazole (MBZ) is extensively used in eel culture for treatment of Pseudodactylogyrus spp. infections. This use may lead to residues of MBZ in eel tissues. Consequently, the residue profile of MBZ in eel after treatment with the drug is of special concern. Therefore, a residue study was performed in European eels (Anguilla anguilla), bath-treated with MBZ at a dose of 1 mg/liter for 24 hr and kept at a water temperature of 25 degrees C. Liver, kidney, fat, skin, and muscle tissues samples were collected at intervals during and after treatment and analyzed for MBZ and its metabolites, hydroxy-MBZ (MBZ-OH) and amino-MBZ (MBZ-NH2), by HPLC. Results showed that MBZ is extensively metabolized to MBZ-OH and MBZ-NH2. Liver and kidney were found to contain the highest levels of MBZ metabolites, and fat contained the highest levels of the parent compound. Skin contained higher residue levels for all three compounds, compared with muscle tissue. MBZ and its hydroxy metabolite were eliminated within 5 days from the edible parts (muscle and skin) of the eels, whereas MBZ-NH2 could be detected by the 14th day after the end of the treatment period. Consequently, although MBZ and MBZ-OH constitute the residues of toxicological concern, MBZ-NH2 should be taken as the compound of interest for estimating the withdrawal time for consumption of eel treated with MBZ.

Crystal structures of the methane monooxygenase hydroxylase from Methylococcus capsulatus (Bath): implications for substrate gating and component interactions.

The crystal structure of the nonheme iron-containing hydroxylase component of methane monooxygenase hydroxylase (MMOH) from Methylococcus capsulatus (Bath) has been solved in two crystal forms, one of which was refined to 1.7 A resolution. The enzyme is composed of two copies each of three subunits (alpha 2 beta 2 gamma 2), and all three subunits are almost completely alpha-helical, with the exception of two beta hairpin structures in the alpha subunit. The active site of each alpha subunit contains one dinuclear iron center, housed in a four-helix bundle. The two iron atoms are octahedrally coordinated by 2 histidine and 4 glutamic acid residues as well as by a bridging hydroxide ion, a terminal water molecule, and at 4 degrees C, a bridging acetate ion, which is replaced at -160 degrees C with a bridging water molecule. Comparison of the results for two crystal forms demonstrates overall conservation and relative orientation of the domain structures. The most prominent structural differences identified between the two crystal forms is in an altered side chain conformation for Leu 110 at the active site cavity. We suggest that this residue serves as one component of a hydrophobic gate controlling access of substrates to and products from the active site. The leucine gate may be responsible for the effect of the B protein component on the reactivity of the reduced hydroxylase with dioxygen. A potential reductase binding site has been assigned based on an analysis of crystal packing in the two forms and corroborated by inhibition studies with a synthetic peptide corresponding to the proposed docking position.

Evaluation of a French version of the Bath Ankylosing Spondylitis Disease Activity Index in patients with spondyloarthropathy.

OBJECTIVE: To develop a French version of the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and to determine its metric properties in patients with all forms of spondyloarthropathies (SpA). METHODS: A French version of BASDAI was obtained after a translation and back-translation process. Patients fulfilling the European Spondylarthropathy Study Group or Amor criteria for SpA were included. BASDAI of Day 0, Day 1, and, when treatment was changed, Day 8, and other clinical and biological disease activity variables were recorded, along with assessment of disease activity by the physician or the patient. Scalability, reproducibility, sensitivity to change, internal consistency and redundancy, and construct validity of the index were assessed. RESULTS: We studied 293 patients. Good scalability, reproducibility, construct, and internal validity were observed for BASDAI. Sensitivity to change could not be assessed. CONCLUSION: The French version of BASDAI exhibited good metric properties in patients with all forms of SpA, confirming its utility in further clinical research in SpA. However, sensitivity to changes due to drug therapy remains to be assessed.
