This study is to analyze the contents related to 'state of water', 'state change of water', and 'conditions of state change' in K-12 science textbooks. For this, we analyzed textbooks based on the 5th kindergarten curriculum, the 6th elementary school science curriculum and the 6th middle school science curriculum. Findings show that some of the contents are designed well by topical sequencing or by spiral sequencing. But others have some problems based on topical sequencing and spiral sequencing. Generally, the contents are represented in the order of Perception of phenomena with senses level, Macroscopic understanding level, Understanding of scientific term level, Microscopic understanding level by grade. But the state change contents related to solidification and melting, and conditions of state change contents related to heat, temperature, wind, and humidity are not represented in the level of Microscopic understanding. The contents of state change and conditions related to heat and wind are not represented in the level of scientific term also.

An 8 month old leopard gecko (Eublepharis macularius) with a large nodule was referred to our hospital. During the physical examination, the nodule had an unclear boundary from the top of the left eye to the front of the left ear and prevented the opening of the left eye. A hard, cheese-like, yellow, pus-filled nodule was observed. A cytological examination of a pus swab sample revealed pyogranulomatous inflammation with rod-shaped bacteria. Ofloxacin was chosen as the empirical topical antimicrobial drug for treatment. The swab samples were inoculated in trypticase soy agar with 5% sheep blood and incubated at 37℃ for 24 h. Gram-negative bacteria were identified via Gram staining, and the Kirby-Bauer antimicrobial susceptible disk diffusion test against 24 antibiotics according to protocol M100-Ed32 of CLSI showed that the fluoroquinolone group (ciprofloxacin and enrofloxacin) was susceptible to the isolated bacteria. Molecular identification based on 16S ribosomal RNA gene sequencing confirmed that the isolated bacteria had a 99.85% nucleotide similarity with Serratia surfactantfaciens (GenBank accession no. CP014948). After 1 week, the boundaries of the nodule became clear; thus, the abscess was physically removed by expanding the hole formed above the eye for drainage, and flushing was repeated. After another 1 week, new tissue restoration without scarring was observed. This is a rare case report of the successful management of a subcutaneous abscess and scar-free healing in a lizard.
