Lichen planus is a unique inflammatory cutaneous and mucous membrane reaction pattern of unknown etiology. Lichen planus of the soles generally occurs as an isolated phenomenon. The lesions differ from classic lesions of lichen planus in that the papules are larger and aggregate into semitransluecent plaques with a globular waxy surface. We report a 38-year-old female patient with lichen planus of right sole. The lesion shows erythematous eroded patch, swelling and severe pain. We thought that she might have envolved erysipelas. So, we gave her oriental medicine and antibiotics, so she was improved. But after long walking, lesion began to getting worse. There appeared oozing, ulcer, pus, pain and swelling in her lesion. We gave her oriental medicine and wet dressinf. But it didn't work.

For the safe disposal of high-level radioactive waste using Engineered Barrier Systems (EBS), bentonite buffer is used by its high swelling capability and low hydraulic conductivity. When the bentonite buffer is contacted to heated pore water containing ions by radioactive decay, chemical alterations of minerals such as illitization reaction occur. Illitization of bentonite indicates the alteration of expandable smectite into non-expandable illite, which threatens the stability and integrity of EBS. This study intends to provide a thorough review on the information underlying in the illitization of bentonite, by covering basic clay mineralogy, smectite expansion, mechanisms and observation of illitization, and illitization in EBS. Since understanding of smectite illitization is crucial for securing the safety and integrity of nuclear waste disposal systems using bentonite buffer, this thorough review study is expected to provide essential and concise information for the preventive EBS design.

Objectives: Vaccination is an important intervention for preventing disease and reducing disease severity. Universal vaccination programs have significantly reduced the incidence of many dangerous diseases among children worldwide. This study investigated the side effects after immunization in infants under 1 year of age in Lorestan Province, western Iran. Methods: This descriptive analytical study included data from all children <1 year old in Lorestan Province, Iran who were vaccinated according to the national schedule in 2020 and had an adverse event following immunization (AEFI). Data were extracted from 1084 forms on age, sex, birth weight, type of birth, AEFI type, vaccine type, and time of vaccination. Descriptive statistics (frequency, percentage) were calculated, and the chi-square test and Fisher exact test were used to assess differences in AEFIs according to the abovelisted variables. Results: The most frequent AEFIs were high fever (n=386, 35.6%), mild local reaction (n=341, 31.5%), and swelling and pain (n=121, 11.2%). The least common AEFIs were encephalitis (n=1, 0.1%), convulsion (n=2, 0.2%), and nodules (n=3, 0.3%). Girls and boys only showed significant differences in mild local reactions (p=0.044) and skin allergies (p=0.002). The incidence of lymphadenitis (p<0.001), severe local reaction (p<0.001), mild local reaction (p=0.007), fainting (p=0.032), swelling and pain (p=0.006), high fever (p=0.005), and nodules (p<0.001) showed significant differences based on age at vaccination. Conclusions: Immunization is a fundamental public health policy for controlling vaccine-preventable infectious diseases. Although vaccines such as the Bacillus Calmette-Guérin vaccine, oral poliovirus vaccine, and pentavalent vaccine are well-researched and reliable, AEFIs are inevitable.

Background: Zhongyi paste is a traditional Chinese medicine herbal paste that is externally applied to reduce inflammation and relieve pain. Methods: An acute foot swelling inflammation model in C57BL/6J mice was established by carrageenan-induced pathogenesis. Zhongyi paste raised the pain threshold and also reduced the degree of swelling in mice with carrageenan-induced foot swelling. Results: Analysis indicated that serum tumor necrosis factor-alpha, interleukin-1 beta, and prostaglandin E₂ (PGE₂) cytokine levels and PGE₂ levels in the paw tissue of the mice were decreased by Zhongyi paste treatment. The quantitative polymerase chain reaction and western blot results showed that Zhongyi paste downregulated the mRNA and protein expression of extracellular signal-regulated kinase 1/2 (ERK1/2), and cyclooxygenase-2 (COX-2), and also downregulated the mRNA expression of PGE₂. At the same time, the Zhongyi paste exerted a stronger effect as an external drug than that of indomethacin, which is an oral drug, and voltaren, which is an externally applied drug. Conclusions: Our results indicated that Zhongyi paste is a very effective drug to reduce inflammatory swelling of the foot, and its mechanism of action is related to regulation of the ERK1/2-COX-2-PGE₂ pathway.

Purpose: Absorbable implants are frequently used to fix facial bone fractures, because they are radiolucent and compatible with magnetic resonance imaging (MRI). Despite their increasing usage, however, there have been few reports about their long-term side-effects. In this paper, a case in which absorbable implants led to a foreign body reaction 17 months after their insertion is presented. Methods: A previously healthy 19-year-old male fell from a flight of stairs and visited the authors' hospital with right periorbital pain. Zygomaticomaxillary fracture involving right orbital floor was detected via a facial bone computed tomography (CT). Internal fixation with absorbable implants was followed by open reduction. 17 months after the surgery, the patient complained of localized periorbital swelling. Removal of the granulomatous lesion including the absorbable implants along with their biopsy and culture was performed. Results: The granulomatous lesion around the implants was firm and extended into the maxillary sinus. The histologic finding showed a microabscess with a foreign body reaction. Methicillin-sensitive Staphylococcus aureus growth was confirmed in the culture. No definite abnormal symptoms ensued after the complete removal. Conclusion: A microabscess-forming granulomatous lesion around the absorbable implant can cause delayed symptomatic foreign body reaction despite its rare occurrence. Complete removal of the lesion including implants is expected to have a successful outcome if it is encountered.

Objectives: We have previous reported that thawed testicular sperm and sperm extracted from seminiferous tubule could achieved optimal fertilization and pregnancy in azoospermic patients. However, thawed testicular sperm did not show motility in many cases. Therefore we studied viability of immotile sperm extracted from frozen-thawed seminiferous tubule using hypo-osmotic swelling (HOS) test and eosin-Y test. Materials and Methods: After sperm extraction using for ICSI, the remained sections of seminiferous tubules were frozen with a computerized freezer. For thawing and preparation of testicular sperm, the seminiferous tubules were thawed by removing from $LN_2$ and letting them at room temperature for 10 min followed by %37^{\circ}C$ water bath for 10 min. The prepared samples were washed for free of preservation medium and sperm preparation method described previous. Sperm was suspended in 0.1 ml hypoosmotic solution. After 30 minutes, the type of distally coiled sperm were assessed. Results: In 44 cases of cryopreservation of seminiferous tubules in obstructive azoospennic patients, the fertilization rates with 2PN were 71.4% and pregnancy rates were 34.1%. The presence of motile spermatozoa on subsequent post-thaw testicular sperm remarked 15.1% and were increased to 77.3% just before ICSI. After sperm extracted from frozen-thawed seminiferous tubule, 3 hrs later in in vitro culture, the cases of presence of motile sperm, reaction of hypo-osmotic swelling test and viable sperm were 63.6% (28/44), 93.2% (41/44), and 77.3% (34/44), respectively. Conclusions: Just after post-thawed testicular sperm did not showed motility. Although motility was gained after in vitro culture, many cases showed non-motile sperm until optimal insemination time. However, HOS test showed positive reaction in non-motile sperm. Therefore, HOS test is an alternative method for the selection of viable sperm for ICSI.

Anglicae dahuricae Radix (ADR), the dried roots of Angelica Dahurica Benth et Hook (Umbelliferae), is a traditional herbal medicine used to treat colds, headache, skin diseases such as acne and possess analgesic, antipyretic and drainage effects. In the present study, the author evaluated the effect of ADR on regulation of inflammatory reaction. ADR reduced the ear-swelling responses derived from compound 48/80 in dose-dependent manner significantly. ADR inhibited the PMA plus A23187-induced productions of IL (Interleukin)-8, IL-1β, granulocyte macrophage-colony stimulating factor (GM-CSF) and tumor necrosis factor (TNF)-α from human mast cells (HMC)-1. In addition, ADR blocked PMA plus A23187-induced ERK1/2 phosphorylation. Ⅰ suggest that ADR regulates inflammatory reaction through inhibition of inflammatory cytokines such as IL-8, IL-1β and GM-CSF.
