Chronic otitis media (COM) with or without cholesteatoma is a major global health problem, especially in developing countries. Until today, there is no other treatment for COM with cholesteatoma (COMch) other than surgery. Puguntano (Curanganfel-terrae Merr) is a plant from Scrophulariaceae family. It can be found in Asia, especially in China, India, Philippines, Myanmar, Malaysia and Indonesia. This plant has traditionally used as stimulant, antidiuretic, treatment for malaria, hepatoprotective drug, antipyretic, antiherpetic drug, anti-cancer, antihyperglycemic, antioxidant and anti-inammatory. The objective of this study is to evaluate the effect of ethanol extract from Puguntano leaves on Interleukin-1α expression level in cholesteatoma matrix cultures with atticoantral type chronic supurative otitis media. This study is an in vitro experimental research comparing two groups, a keratinocyte cholesteatoma culture with and without Puguntano extract. A group without extract Puguntano was divided into 4 different groups: group with Puguntano extract 1 mg/ml, 2 mg/ml, 4 mg/ml and control group.Interleukin-1α level in cholesteatoma culture is inversely proportional to Puguntano extract. Interleukin-1α expression level in group with Puguntano extract 1 mg/ml is 4,335 pg/ml; 2 mg/ml is 3,83 pg/ml; and 4 mg/ml is 2,74 pg/ml. Those results showed the decreasing level of Interleukin-1α expression compared to control group, which is 8,2889 pg/ml.

Anaphylaxis is the most common allergic reaction triggered by allergens such as insect poisons, food, and drugs through skin contact, injection, or inhalation. In vitro previous research showed that strawberries fruit have activity as antioxidant, anticancer, anti-inflammation, and anti-allergic. The research aimed to determine the antianaphylaxis strawberry fruit extract in mice (Balb/C strain) with ovalbumin-induced.  Twenty-four Balb/C strain mice were divided into six groups (n=4). Group I and II as a normal and control group. Group III till VI as a treatment group was given cetirizine dose 0.042 mg/20 g BW and strawberry extract doses 0,68; 1,36; and 2,72 mg/20 g BW, respectively. This research showed that 70 % of ethanol extract of strawberries fruit have antiallergic activity in response to active cutaneous anaphylaxis. 70% ethanol extract of strawberries doses 2.72 mg/20 g BW had similar antiallergic activity compare with cetirizine. The conclusion of this study showed that strawberries fruit extract could be developed as an alternative medicine to anti-anaphylaxis or anti-allergic.

AbstractAim:This study aimed to determine whether or not the middle cranial fossa dural plate is located lower (i.e. more caudally) in patients with chronic otitis media, relative to adjacent structures.Methods:The authors retrospectively investigated computed tomography temporal bone scans of 267 ears of 206 patients who had undergone surgery with a diagnosis of chronic otitis media, together with scans of 222 ears of 111 patients without chronic otitis media. The depth of the middle cranial fossa dural plates was recorded.Results:The mean depth of the middle cranial fossa dural plate was 4.59 mm in the study group and 2.71 mm in the control group (p < 0.001). The middle cranial fossa dural plate was located lower in the right ear in both the study and control groups.Conclusion:The middle cranial fossa dural plate was located lower in patients with chronic otitis media, and in the right ears of both patients and controls. Surgeons should take this low location into consideration, and take extra care, during relevant surgery on patients with chronic otitis media.

AbstractBackground:This study investigated genetic polymorphisms affecting the inducible nitric oxide synthase, superoxide dismutase and catalase enzymes in chronic otitis media patients with and without tympanosclerosis, and the role of genetic susceptibility in the disease aetiology.Methods:A total of 162 patients who underwent surgery for chronic otitis media were divided into two study groups: a tympanosclerosis group and a chronic otitis media group. A third, the control, group comprised 188 healthy volunteers. Venous blood samples were evaluated using reverse transcriptase polymerase chain reaction.Results:There was a significant difference in GG genotype distribution of the −277A>G polymorphism in the NOS2 gene between the tympanosclerosis and control groups (p < 0.05). However, there were no significant between-group differences in the CC genotype distribution of the p.Ala16Val (C>T) polymorphism in the SOD2 gene (p > 0.05). There were significant differences in the TT genotype distribution of the −21A>T polymorphism in the CAT gene between the tympanosclerosis and control groups, and between the chronic otitis media and control groups (p < 0.05).Conclusion:These results suggest that genetic predisposition may play a role in the aetiopathogenesis of tympanosclerosis.

AbstractObjectivesTo evaluate the nasal functions of patients with unilateral chronic otitis media using rhinomanometry, comparing chronic otitis media sides with healthy sides, chronic otitis media patients with cholesteatoma and without cholesteatoma, and patients with healthy individuals.MethodsThis prospective study included 102 patients with unilateral chronic otitis media (48 with and 54 without cholesteatoma). The control group comprised 40 individuals without any ear or nasal pathologies. All patients underwent active anterior rhinomanometry to measure nasal airway resistance and a saccharin test to measure mucociliary transport times.ResultsThere were no significant differences in nasal airway resistance and mucociliary transport time between the chronic otitis media sides and unaffected sides in the 102 patients (p = 0.72 and p = 0.28, respectively), between the non-suppurative chronic otitis media patients (without cholesteatoma) and chronic otitis media with cholesteatoma patients (p > 0.05), or between the study and control groups (p > 0.05).ConclusionThe present study, with a larger sample size compared to previously published literature, supports the conclusion that unilateral nasal obstruction is unlikely to lead to chronic otitis media on the same side. The results also suggest that nasal functions do not contribute to the development of cholesteatoma.

Background. Retained hemothorax (RH) is a common problem in cardiothoracic and trauma surgery. We aimed to determine the optimum agitation technique to enhance thrombus dissolution and drainage and to apply the technique to a porcine-retained hemothorax. Methods. Three agitation techniques were tested: flush irrigation, ultrasound, and vibration. We used the techniques in a benchtop model with tissue plasminogen activator (tPA) and pig hemothorax with tPA. We used the most promising technique vibration in a pig hemothorax without tPA. Statistics. We used 2-sample t tests for each comparison and Cohen d tests to calculate effect size (ES). Results. In the benchtop model, mean drainages in the agitation group and control group and the ES were flush irrigation, 42%, 28%, and 2.91 ( P = .10); ultrasound, 35%, 27%, and .76 ( P = .30); and vibration, 28%, 19%, and 1.14 ( P = .04). In the pig hemothorax with tPA, mean drainages and the ES of each agitation technique compared with control (58%) were flush irrigation, 80% and 1.14 ( P = .37); ultrasound, 80% and 2.11 ( P = .17); and vibration, 95% and 3.98 ( P = .06). In the pig hemothorax model without tPA, mean drainages of the vibration technique and control group were 50% and 43% (ES = .29; P = .65). Discussion. In vitro studies suggested flush irrigation had the greatest effect, whereas only vibration was significantly different vs the respective controls. In vivo with tPA, vibration showed promising but not statistically significant results. Results of in vivo experiments without tPA were negative. Conclusion. Agitation techniques, in combination with tPA, may enhance drainage of hemothorax.

Abstract Background More and more studies have confirmed that miRNAs play an important role in maintaining bone remodeling and bone metabolism. This study investigated the expression level of miR-206 in the serum of osteoporosis (OP) patients and explored the effect and mechanism of miR-206 on the occurrence and development of osteoporosis. Methods 120 postmenopausal women were recruited, including 63 cases with OP and 57 women without OP. The levels of miR-206 were determined by qRT-PCR technology. Spearman correlation coefficient was used to evaluate the correlation of miR-206 with bone mineral density (BMD). An ROC curve was used to evaluate the diagnostic value of miR-206 in osteoporosis. The effects of miR-206 on cell proliferation and cell apoptosis of hFOBs were measured by CCK-8 assay and flow cytometry, respectively. Luciferase reporter gene assay was used to confirm the interaction of miR-206 and the 3′UTR of HDAC4. Results Serum miR-206 had low expression level in osteoporosis patient group compared with control group. The expression level of serum miR-206 had diagnostic value for osteoporosis, and the serum miR-206 levels were positively correlated with BMD. The down-regulated miR-206 could inhibit cell proliferation and promote cell apoptosis. Luciferase analysis indicated that HDAC4 was the target gene of miR-206. Conclusions MiR-206 could be used as a new potential diagnostic biomarker for osteoporosis, and in in vitro cell experiments, miR-206 may regulate osteoblast cell proliferation and apoptosis by targeting HDAC4.

Abstract Objective This study aimed to analyse social, health and environmental factors associated with the development of chronic otitis media by age nine. Method This was a prospective, longitudinal, birth cohort study of 6560 children, reviewed at age nine. Chronic otitis media defined as previous surgical history or video-otoscopic changes of tympanic membrane retraction, perforation or cholesteatoma. Non-affected children were used as the control group. Results Univariate analysis demonstrated an association between chronic otitis media and otorrhoea, snoring, grommet insertion, adenoidectomy, tonsillectomy, hearing loss, abnormal tympanograms and preterm birth. Multivariate analysis suggests many of these factors may be interrelated. Conclusion The association between chronic otitis media and otorrhoea, abnormal tympanograms and grommets supports the role of the Eustachian tube and otitis media (with effusion or acute) in the pathogenesis of chronic otitis media. The role of snoring, adenoidectomy and tonsillectomy is unclear. Associations suggested by previous studies (sex, socioeconomic group, parental smoking, maternal education, childcare, crowding and siblings) were not found to be significant predictors in this analysis.

SUMMARY Uptake of tritiated lysine vasopressin ([3H]LVP) was studied in halved neural lobes of rats (which had been given either tap water (control group) or 2% (w/v) NaCl solution as drinking water for 4 days) as well as in slices of pig neural lobe. Uptake of radioactivity into the neural lobes was shown but analysis of the extracts of incubated lobes of both species by ion exchange chromatography showed that very little of it remained in the tissue as hormone. In addition, some radioactivity was associated with trichloroacetic acid-insoluble proteins. After 90 min of incubation, and after correction for the breakdown, the uptake of unchanged [3H]LVP, expressed as a tissue: medium ratio, was 0·14 ± 0·04 and 0·09 ± 0·03 (mean ± s.e.m.) for the saline-treated and control rats respectively, while the tissue: medium ratios for the breakdown product(s) were 6·47 ± 0·45 and 5·50 ± 0·36. The results suggest uptake of [3H]LVP into the cell with almost complete intracellular breakdown of the hormone.

There has been much debate over a direct role for progesterone (P4) in early bovine embryo development. While previous attempts to supplement bovine embryos in vitro with P4 produced results that vary and are often contradictory, this may be a response of administering P4 at inappropriate times. Therefore, the objective of these experiments was to determine if P4 could exert a direct effect on developing IVF-derived bovine embryos when administered at an appropriate time of embryo development. In Exp. I, IVF-derived bovine 8-cell embryos were randomly allotted to treatments: (1) control, CR1aa medium (n = 168); (2) vehicle, CR1aa + ETOH (0.01%) (n = 170); and (3) P4, CR1aa + ETOH + P4 (20 ng/mL in 50-μL droplet) (n = 173). In Exp. II, IVF-derived bovine 8-cell embryos were randomly allotted to treatments: (1) control, CR1aa medium (n = 160); (2) vehicle, CR1aa + DMSO (0.01%) (n = 180); and (3) P4, CR1aa + DMSO (0.01%) + P4 (20 ng/mL in 50-μL droplet) (n = 170). All embryos were evaluated on Days 6 to 9 post-insemination and rates calculated from 8-cell embryos. In Exp. I, ETOH tended to have a detrimental effect with significantly fewer (P < 0.05) embryos (53%) developing to the blastocyst stage on Day 7 compared with the control (62%) and P4 (71%) groups. At Day 7, significantly more embryos cultured in P4 (71%) developed to the blastocyst stage compared with the control group (62%). P4 treatment significantly increased the number of Grade 1 blastocysts (25%) on Day 7 compared with vehicle (15%) and control (17%) groups. At the end of culture, there were also significantly more Day 9 hatched blastocysts in the P4 group (33%) compared with vehicle (22%) and control (21%) groups. Supplementing P4 in the culture medium increased the rate of development, resulting in significantly more blastocysts (8%) on Day 6 and hatched blastocysts (21%) on Day 8 compared with vehicle (3% and 12%) and control (0% and 8%) groups, respectively. In Exp. II, there were no significant differences between treatment groups for Day 7 blastocysts (control 54%, DMSO 61%, P4 57%) and Day 9 hatched blastocysts (control 46%, DMSO 51%, P4 46%). However, there were significantly more Grade 1 blastocysts in the P4 group (22% and 36%) on Days 6 and 8 compared with vehicle (11% and 23%) and control (13% and 23%) groups, respectively. The lack of improvement in Day 7 blastocysts and Day 9 hatched blastocysts rates leads to further uncertainty in understanding the P4 vehicle interactions. In conclusion, the results of these two experiments indicate that P4 can exert a direct effect on the developing IVF-derived bovine embryo; however, due to P4 vehicle interactions; other inert vehicles need to be explored to further evaluate the direct effects of P4 on the developing bovine embryo.
