Calcium-channel blockers such as nifedipine could be associated with gingival overgrowth. The aim of this study was to examine the role of nitric oxide (NO) on nifedipine-induced gingival hyperplasia along with submandibular secretory function in rats. Animals in divided groups received nifedipine (250 mg/kg diet) alone and in combination with L-arginine (2.25% w/v) or N(omega)-nitro-L-arginine methyl ester (L-NAME) (0.7% w/v) in drinking water for 20 days. Controls received only tap water. Pure submandibular saliva was collected intraorally by micropolyethylene cannula and the mandibular gingiva was examined by means of dissecting microscope for signs of redness, thickness, inflammation and exuda. Twenty-day nifedipine treatment induced gingival hyperplasia accompanied with reduced salivary flow rate and concentrations of total protein, epidermal growth factor (EGF) and calcium in comparison with controls. Co-treatment of animals with nifedipine and L-arginine protected from gingival hyperplasia and retained flow rate, and concentrations of total protein, EGF and calcium in normal levels. Co-treatment of animals with nifedipine and L-NAME potentiated nifedipine-induced gingival hyperplasia and reductions in flow rate and concentrations of total protein, EGF, and calcium. It is concluded that nifedipine-induced gingival hyperplasia is associated with salivary dysfunction. Activation of cGMP-dependent positive signal-transduction mechanisms in salivary glands might be the mechanism for protective effects of NO against nifedipine-induced gingival hyperplasia.

Background:Palpitation is a sign of a disease and is very common in general population. For this purpose we decided to explain it in this study.Objectives:The purpose of this study was to describe the palpitation in both modern and traditional medicine aspect. It may help us to diagnose and cure better because the traditional medicine view is holistic and different from modern medicine.Materials and Methods:We addressed some descriptions to the articles of traditional medicine subjects which have published recently. Palpitation in modern medicine was extracted from medical books such as Braunwald, Harrison and Guyton physiology and some related articles obtained from authentic journals in PubMed and Ovid and Google scholar between1990 to 2013.Results:According to modern medicine, there are many causes for palpitation and in some cases it is cured symptomatically. In traditional medicine view, palpitation has been explained completely and many causes have been described. Its aspect is holistic and it cures causatively. The traditional medicine scientists evaluated the body based on Humors and temperament. Temperament can be changed to dis-temperament in diseases. Humors are divided in 4 items: sanguine, humid or phlegm, melancholy and bile. Palpitation is a disease, it is heart vibration and is caused by an abnormal substance in the heart itself or its membrane or other adjacent organs that would result in the heart suffering.Conclusions:Our data of this article suggests that causes of palpitation in the aspect of traditional medicine are completely different from modern medicine. It can help us to approach and treat this symptom better and with lower side effects than chemical drugs. According to this article we are able to detect a new approach in palpitation.

Introduction:The use of traditional medicine has been emerged in the treatment of BPS (bladder pain syndrome) due to its high prevalence and expenses and its insufficient treatment by conventional therapies. Iranian traditional medicine has discussed such diseases. Considering the signs and symptoms of BPS and “reeh”, the proposed mechanism of flatulency as casualty of recurrent circulating pains seems to be a proper diagnose. So, as a preliminary study the authors administered Horse Mint as one of effective traditional herbs on flatulent pain in a patient with BPS.Case Presentation:A 60-year-old female was referred with the diagnosis of BPS. Six clinical visits with 2-week intervals were performed for patient, and the NIH-ICSI (National Institutes of Health Interstitial Cystitis Symptom Index) was completed, which was used as a pretreatment symptom quantifier and post-treatment outcome tool. Horse mint (Mentha longifolia) was prescribed twice a day for 12 weeks.Discussion:Clinical visits showed alleviation of signs, symptoms, and changes in the patient's NIH-ICSI score, suggesting further studies on this field.

In the present study, the effects of Ciprofloxacin (Cipro), a fluoroquinolone antibiotic, on rat submandibular gland structure and function were examined in an acute experiment. Cipro was administered intraperitoneally at various doses (20, 40 and 80 mg/kg). Pure submandibular saliva was collected intraorally by micropolyethylene tubes under anaesthesia using a dissecting microscope. After collection of saliva, submandibular glands were removed and weighed. Flow rate, amylase activity, total protein and electrolyte concentrations were measured in saliva. Concentrations of DNA and protein were measured in the gland. All doses of Cipro (20, 40, 80 mg/kg) reduced salivary flow rate. Concentrations of salivary total protein and calcium and gland DNA were reduced by all doses of Cipro. Treatment by Cipro (80 mg/kg) induced an increase in salivary sodium and potassium concentrations. Histopathological examination of glands revealed that Cipro at doses of 40 mg/kg and 80 mg/kg induces morphological changes in the glands including irregular shape of the cerous and mucous bobbles, lack of nucleus in some cells, damage of the cytoplasmic and cell walls and presence of oncocytes in secretory ducts. It is concluded that Cipro inhibits rat submandibular gland functions consistent with structural damages to the gland that might be observed as a side effect in humans. Properties of fluoroquinolones to alter intracellular cAMP and their ability to suppress DNA and protein synthesis of acinar cells might be possible reasons for observed changes.

Introduction:Unknown etiology and pathophysiology of prostate pain syndrome (PPS) has led to a lack of proper and competent treatment in modern medicine. According to the guidelines of European Association of Urology (EAU), use of complementary treatments is recommended for PPS. In this preliminary study, analyzing the signs and symptoms of PPS from the viewpoint of Iranian traditional medicine (ITM) was helpful in selecting the appropriate alternative treatment.Case Presentation:Two male patients diagnosed with PPS were evaluated and treated according to the ITM. Each patient took 15 mL oxymel 45 minutes after lunch and dinner. For each patient, four clinical visits were made with one week intervals and the validated Farsi version of international prostate symptom score (IPSS) and numeric pain rating score (NPRS) were completed for them.Conclusions:Considering the fact that other major pathological causes are ruled out, many of the symptoms and signs observed in these patients were similar to those associated with flatulency-related diseases in ITM. Selecting treatment with oxymel was based on this view and led to improvements in the digestive and urinary symptoms according to Farsi version of the IPSS and NPRS.
