Effects of hypertonic dextrose and paraffin solution as non-antibiotic treatments of clinical endometritis on reproductive performance of high producing dairy cows.

The objective of this study was to compare the reproductive performance of cows affected by clinical endometritis (CE) following treatment with an intrauterine infusion of 50% dextrose solutions (DEX) and liquid paraffin (LP) as alternative therapies with routine treatments including PGF2α injection and intrauterine infusion of oxytetracycline (OTC). Moreover, the reproductive indices of cows treated with endometritis were compared with those of healthy ones. At postpartum reproductive tract examination (28-35 DIM) in one Iranian dairy farm, cows with CE without any selection were assigned to four groups: (a) OTC, a common treatment in Iran, was administered (5 g) to 396 cows, (b) PGF2 α (PG) was injected to 496 cows, (c) dextrose solution (DEX): intrauterine infusion of 50% dextrose solution (200 ml) was done in 427 cows, and (d) liquid paraffin (LP) was administered (100 ml) to 423 cows via intrauterine route. We further assigned 2,233 clinically healthy cows to the control group. The incidence of endometritis was 41.6% in this study. Based on the results of reproductive indices including median days to first AI, days open (DO), first service conception rate, conception rate in 2nd and 3rd services, conception rate in all three services, pregnancy rate < 100 days and pregnancy rate < 200 days, except for median days to first AI in other reproductive indexes, reproductive performance was significantly lower in LP group compared with the healthy cows and other treatment groups (p < 0.05). Except for the first service conception rate and proportion of cows pregnant before 100 days in milk (DIM), there existed no significant difference between the DEX group and the control as far as reproductive performance is concerned (p ≥ 0.05). The first service conception rate was recognizably lower in DEX group compared with OTC and PG (p < 0.05). In conclusion, the use of a non-antibiotic special solution of dextrose 50% is a good alternative to antibiotic agents concerning the treatment of CE in dairy cows.

[Paraffin oil injecions due to bigorexia may cause hypercalcaemia].

Paraffin oil injections may cause severe hypercalcaemia, likely due to development of granulomas at injection sites, activating 1,25 dihydroxyvitamin D and increasing calcium uptake from gut, kidney and bone. This is a case report of a 39-year-old male with severe hypercalcaemia and renal failure due to paraffin oil injections. He was treated with prednisolone (25-50 mg daily), but the disease recurred the next two summers probably due to erroneous vitamin D supplement and sun exposure. The disease course and prognosis are unknown. Treatment options are discussed, and paraffin oil injections should be avoided.

Detection thresholds for four different fatty stimuli are associated with increased dietary intake of processed high-caloric food.

BMI-specific differences in food choice and energy intake have been suggested to modulate taste perception. However, associations between body composition and fat taste sensitivity are controversial. The objective of this study was to examine the association between body composition, dietary intake and detection thresholds of four fatty stimuli (oleic acid, paraffin oil, canola oil, and canola oil spiked with oleic acid) that could be perceived via gustatory and/or textural cues. In 30 participants, fat detection thresholds were determined in a repeated measurements design over twelve days. Weight status was examined by measuring the participants' BMI, waist circumference and waist-to-hip ratio. The habitual food intake was assessed via several questionnaires and twelve, non-consecutive 24-hour food diaries. In this study, a negative correlation was found between fat detection thresholds and the intake of food rich in vitamins and fibre. Moreover, a positive correlation was identified between the intake of high-fat food and fat detection thresholds. No differences in fat detection thresholds were observed due to variations in BMI or waist-to-hip ratio. These findings indicate that a regular intake of fatty foods might decrease an individuals' perceptual response to fats which might lead to excess fat intake on the long term.

[Anti-inflammatory and analgesia effects of electroacupuncture device of point injection on rats of inflammatory pain].

OBJECTIVE: To explore the anti-inflammatory and analgesia mechanism of electroacupuncture (EA) device of point injection (PI) on rats of inflammatory pain. METHODS: 48 Sprague Dawley (SD) rats were randomly assigned into a control group, a model group, an EA+PI group, an EA device of PI (EAPI) group, an EA group and a PI group, eight rats in each one. The rats in the control group were subcutaneously injected with 50 µL of liquid paraffin oil solvent into the dorsum of left hindpaw, while rats in the remaining groups were treated with 50 µL of complete freund's adjuvant (CFA) at identical location to induce the model of inflammatory pain. After model establishment, the rats in the EA+PI group, EAPI group, EA group and PI group were treated with EA+PI,EA device of PI, EA and PI, respectively, once every other day (the 2nd day, 4th day and 6th day). Each treatment was given for 30 min. The mechanical withdrawal threshold, thermal withdrawal threshold and foot swelling before and 1 d to 6 d after model establishment were observed; the western blotting method was applied to measure IL-1ß expression in inflammatory tissue of skin. RESULTS: After model establishment, compared with the control group, the mechanical withdrawal threshold and thermal withdrawal threshold were reduced (all P<0.05) and the foot swelling was increased in the rest groups (all P<0.05). After treatment, the mechanical withdrawal threshold and thermal withdrawal threshold in the EAPI group were significantly increased compared with those in the EA+PI group, EA group and PI group (all P<0.05), but the foot swelling was reduced (all P<0.05). The IL-1ß expression in the model group was higher than that in the control group (P<0.05); after treatment, the IL-1ß expression in the EAPI group was lower than that in the model group, EA group and PI group (all P<0.05), but no significantly different from that in the EA+PI group (P>0.05). CONCLUSIONS: The efficacy of EA device of PI on inflammatory pain is superior to EA combined with PI, EA alone and PI alone, which is suitable for further popularization and application.

Anti-inflammatory effect of Euphorbia hirta in an adjuvant-induced arthritic murine model.

Despite extensive research into inflammatory diseases to date, no drugs with favourable safety profiles are available for treatment. Euphorbia hirta (E. hirta) is a tree that is locally used as a traditional medicine in Africa and Australia to treat numerous diseases such as hypertension, antipyretic and anti-inflammatory activities. The aim of the present study was to determine the potential anti-arthritic effects of E. hirta in mouse models of adjuvant induced arthritis (AIA). We treated BALB/c mice with (p.o.) E. hirta (25, 50, 100, and 200 mg/kg) daily (13 days) beginning at the onset of AIA. We examined the effect of E. hirta on key mediators of arthritic-inflammation, including pro-inflammatory (IL-2, IFN-γ, and TNF-α) and anti-inflammatory (IL-4 and IL-5) cytokines, T-cell activation markers (CD25/CD69), and co-stimulatory molecules (CD80/CD86). We also examined the inflammatory mediators (PGE2 and LTB4) response. E. hirta-treated mice showed a substantial reduction in the levels of pro-inflammatory cytokines, down regulated cell activation markers and co-stimulatory molecules, and up regulated anti-inflammatory cytokines. E. hirta decreased the levels of inflammatory-mediators in AIA animals. Supplementation with an E. hirta extract may be a promising treatment for arthritic and inflammatory diseases.

Lipid uptake and skin occlusion following topical application of oils on adult and infant skin.

BACKGROUND: Topical application of oils and oil-based formulations is common practice in skin care for both adults and infants. Only limited knowledge however is available regarding skin penetration and occlusive potential of oils and common methods for measuring skin moisturization fall short when it comes to the moisturizing effect of oils. OBJECTIVE: In this study we used in vivo confocal Raman microspectroscopy to test the efficacy of paraffin oil (mineral oil) and two vegetable oils in terms of skin penetration and occlusion. Petrolatum was used as a positive control. METHODS: The products were applied topically on the forearms of nine volunteers and seven infants and Raman spectra were acquired before and at 30 and 90 min following application. Depth concentration profiles for lipid and water were calculated from the Raman spectra. Skin occlusion was assessed from the amount of stratum corneum (SC) swelling measured from the water concentration profiles. RESULTS: The paraffin oil and the vegetable oils penetrate the top layers of the SC with similar concentration profiles, a result that was confirmed both for adult and infant skin. The three oils tested demonstrated modest SC swelling (10-20%) compared to moderate swelling (40-60%) for petrolatum. CONCLUSION: These data indicate that there is no statistical difference between the paraffin oil and vegetable oils in terms of skin penetration and skin occlusion. The results for petrolatum show that in vivo confocal Raman microspectroscopy is sensitive and specific enough to measure both lipid uptake and skin occlusion events following topical application.

The reduction of itch during burn wound healing.

The purpose of this study was to find a method to reduce the itch experienced by patients who have sustained burn injuries, by using and comparing the effectiveness of 2 shower and bath oils. One product contained liquid paraffin with 5% colloidal oatmeal and the other contained liquid paraffin. The study was carried out in the Adult Burns Unit, Royal Brisbane Hospital (RBH), Brisbane. It was conducted during a 10-month period from July 1998 until April 1999. Thirty-five acute burns patients participated in an assessor-blind clinical trial. Patients were asked twice daily to rate their discomfort from itch and pain. The amount of antihistamine requested by each patient was totalled daily. Analysis of data supplied by patients showed that the group using the product with colloidal oatmeal reported significantly less itch and requested significantly less antihistamine than those using the oil containing liquid paraffin.

Removal of perforated adhesive tape: dry versus solvent-assisted.

This study compared the speed of dry removal of perforated adhesive tape from skin with some of the more commonly used solvents, namely acetone, arachis (peanut) oil, paraffin oil and saline. Twenty healthy volunteers had each of the solvents used on separate adhesive tapes applied circumferentially to their arms. Time to removal was recorded and analysed using the non-parametric sign test. The findings indicate that removing the tape dry was faster than using solvents, with the exception of acetone. Additionally, the researchers had difficulty cleaning the skin following the removal of tape when solvents were used. The solvents tended to cause some disintegration of the tape adhesive, which remained attached to the volunteers' skin and was difficult to remove. The researchers' preference is for dry removal of perforated adhesive tapes.

Clinical spectrum of connective tissue disease after cosmetic surgery. Observations on eighteen patients and a review of the Japanese literature.

Connective tissue disease has been reported to occur following cosmetic surgery with injection of the foreign substances paraffin and silicone (human adjuvant disease). The clinical findings in 18 such patients and a review of 28 additional cases from the Japanese literature are presented. The patients were classified into 2 major groups: group I consisted of 24 patients with definite connective tissue disease--12 with scleroderma, including 8 with progressive systemic sclerosis (PSS), 6 with rheumatoid arthritis, 5 with systemic lupus erythematosus, and 1 with polymyositis; group II consisted of 22 patients with human adjuvant disease with some symptoms, signs, and laboratory abnormalities suggestive, but not diagnostic of a connective tissue disease. The occurrence of PSS is approximately three-fold greater than expected for all women believed to have undergone such surgery, and PSS developed primarily in individuals injected with paraffin. Prolonged exposure to the injected substance may play a role in the induction of these immunologic disorders.
